This major innovation in polyethylene polymerization was commercialized rapidly and already represents a significant portion of Dow’s global LDPE business. Moreover, this advance in LDPE production ...

Production that involved promotion of the polymerization at mild temperatures and pressures came in 1938, but was soon hushed. Because polyethylene was found to have very low-loss properties at very ...

Condensation polymerization, also referred to condensation-elimination polymerizations or step-reaction polymerization, uses an elimination reaction to create the polymer. In this polymerization ...

As chain-growth polymerization generally forms aliphatic main chains containing units such as alkylene and alkenylene, the method has rarely been applied to the construction of arylene units. Thus ...

One of the most successful plastics is polyethylene terephthalate (PET), the material we use to make bottles and fibers for clothing. However, PET is made from petroleum-based building blocks. An ...

Univation is also the world’s leading manufacturer and supplier of conventional and advanced polyethylene polymerization catalysts designed specifically for the UNIPOL™ PE Process. ...

Promising mechanical properties in the present biobased polyesters byond polyethylene Effect of molecular weight toward tensile properties in the present biobased polyesters, HP1.

The nickel-based catalyst is described in a paper published Friday, Jan. 25, in Nature Communications. "This is a completely new class of catalysts that can produce ultra-high-weight polyethylene ...

Plastic production belches out over 5% of global greenhouse ... the scientists found that most of the emissions come from steps that happen before the starting materials go through polymerization.

Each reactor line is designed to achieve nameplate capacities of 350,000 tons per annum for a combined polyethylene (PE) production capacity of 700,000 tons per annum.
