CEP: Chem Economics - Plastic Additives are Poised for Growth

Chem Economics
T. Kevin Swift
Not all polymers are useful and/or processable in their natural form. Thus, functional chemicals are added to polymer resins to facilitate processing and to enhance, extend, or otherwise modify the properties of the plastic products manufactured from polymer resins. Such plastic additives represent a $4.6-billion business in the U.S.

CEP: Catalyzing Commercialization - A Biodegradable Plastic Made from Waste Methane

Catalyzing Commercialization
What if we could make the Great Pacific Garbage Patch just disappear? What if plastics didn’t accumulate in our landfills? What if we could reduce greenhouse gas emissions while replacing up to 30% of the world’s plastics with a biodegradable substitute? Researchers have tried for decades to achieve these goals. One approach being taken is the development of an efficient production process for poly-hydroxyalkanoate (PHA) — a biodegradable polymer similar to the polypropylene used to make yogurt containers.

Making Plastics: From Monomer to Polymer

Back To Basics
Pete Sharpe
Versatility, ease of manufacture, and relatively low cost make plastics some of the most useful materials for a wide range of applications. This article explains the chemistry and production processes behind two of the most popular plastics — polyethylene and polypropylene.
