$32,000,000 of Polyethyline Black Balls in the Water Reservoir

This is a fascinating video describing why they poured 96 million black polyethylene balls (they call them shade balls) into the Los Angeles drinking water reservoir. There was more than one reason.

The South Texas Section Celebrates 50 Years of the Polyolefins Conference


The 2025 SPE International Polyolefins Conference celebrated the 50th anniversary of this event. Over the years, many innovations and developments have been featured or introduced at the Polyolefins Conference. Therefore, a special session was developed to capture some of the history of the industry, from catalysts and polymerization to applications and markets.

Bullish on Innovation

Masud Monwar and Max McDaniel (ChevronPhillips Chemicals) recalled the discovery of HDPE by Paul Hogan and Bob Banks at Phillips. They had been testing alternative metals to modify a nickel catalyst used to dimerize propylene for aviation fuel to boost octane. When they added chromium to the catalyst, the propylene consumption didn’t balance the gasoline production, but then they found a white solid in the reactor. Phillips management was so bullish on the discovery, they signed nine licensors in seven countries before the first plant came on stream!

Vintage HDPE homopolymers were improved with butene and hexene comonomers to generate a platform of copolymers ultimately extending to LLDPE. Those innovations became the cornerstone for other developments including co-catalysts for better efficiency and properties and improved control of molecular structure. New catalyst supports activated metallocenes, resulting in many more complex hybrid structures.

Digging deeper into the technology has enabled CPChem to model the fundamentals of the catalyst and reactor interactions, including the roles of solvents, etc. And so, the work continues.

Ziegler-Natta: The Chrome Alternative

Ziegler-Natta catalysts have been the other major catalyst system for polyolefins over the past 50 years. Jochem Pater reviewed the history of Ziegler-Natta catalysts, particularly in bulk slurry polymerization. About the same time Hogan and Banks recognized the potential of chrome, Ziegler and Natta produced and characterized amorphous and crystalline polypropylene. The amorphous content drove innovation in separation of the amorphous content (deashing) and catalyst developments to minimize the production of amorphous content.

Hercules and Montecatini developed new processes to drive production rates in addition to isotacticity. Further developments in catalysts systems refined product properties as well as operating efficiencies. Slurry loop reactors became one of the two basic technologies delivering the large-scale polyolefin quantities required for this largest portion of the overall global polymer demand. These loop reactors were built in series by process developers like Hercules and Montecatini for tailored compositions as well as increased through-put. The introduction of liquid propylene enabled higher concentrations, higher catalyst activity, simpler processes (diluent recycle), and ultimately the global production rates we enjoy today.

Slurry loop reactors: enabling scale and in-line tailoring

While catalyst developments focused on optimizing product compositions, reactor engineering was expanding options at scale. HDPE tubing was linked in a loop to make hula hoops and consume stirred-slurry HDPE, but the real opportunity was pipe, which has continued for 70 years and promised large demand.

Stirred slurry reactors were configured in series which ultimately led to larger loop reactors. Loop configurations with in-cycle cooling enabled higher production rates via continuous removal of heat of reaction. Series of loops could accommodate much different reactor environments further differentiating fractions of the overall product composition.

More recently, loop reactors have been augmented with gas-phase reactors to produce heterophasic polymers with elastomers, etc. This wide range of compositions allowed single-train production of what had previously required secondary compounding.

Solution reactors: Accommodating low melting point polyolefins

In the mid 1950’s, DuPont developed solution polymerization for low melting point polymers built on Ziegler-Natta catalysts. The key was accommodating solutions rather than requiring slurries. Solvents were selected to facilitate operations and separations, and series reactors were developed to expand cooling options which facilitated higher production rates. By the early 70’s, Mitsui began pushing the densities lower, even below LLDPE; and the discoveries of metallocene catalysts by ExxonMobil and Dow further pushed PE densities to 0.865 g/cc and below.

Solution reactors are smaller than gas-phase reactors, with lower residence times for fast transitions between product compositions. They accommodate the tackier compositions associated with very low density. High viscosities of very high molecular weight limit the product range, and higher reactor pressures and solvent recovery require additional hardware and cost.

As with other process platforms, series solution reactors enable multi-modal compositions for tailored product properties and processability. Examples include tailored sealing temperature curves for package integrity and speeds as well as balanced toughness with density for moisture barrier. Tailored MWD can also facilitate solid-state orientation for package appearance and stiffness/toughness.

Gas-phase reactors enable larger-scale production and energy efficiency

Gas-phase reactors tend to be larger due to lower operating pressures. Recycling the reactor gas in-line allows high heat removal for faster reaction rates. While gas-phase reactors have been developed with vertical and horizontal stirred operations (especially for polypropylene), the most common design is a fluidized bed. Fluidized beds approach perfectly stirred reactors. This limits their transition times between reactor compositions, however it also supports composition control. The first Union Carbide Unipol™ gas-phase reactor started up in 1968, producing HDPE. Within 10 years, higher comonomer addition rates pushed the product window to include LLDPE. Higher production rates (via enhanced cooling) and lower-density products were achieved with limited liquid recycle, known as “condensed mode”. In 1995, Exxon commercialized metallocene catalyst operations for gas-phase PE, expanding capacities (for the same reactor size) as “super-condensed mode”. Today as much as a third of global PE production is produced via gas-phase polymerization.

Looking forward

The SPE International Polyolefins Conference was inaugurated in 1975 when the US Gulf Coast (from Lake Charles to Corpus Christi) produced a very large portion of the global polyolefin supply. It remains a major global supply point as well as a global technology center. Join us at the 2026 International Polyolefins Conference as we discuss ongoing developments and the technologies supporting them.
