Investigation on Catalyst Selection for Polymerization Processes in Petrochemical Industries
Abstract: Organic polymers are long-chain compounds made of several repeating units. These polymers are either natural, such as protein, cellulose, starch or synthetic, such as polyethylene (a plastic), polyesters and polyamides (plastics and fibers) and polybutadiene (rubber).Many organic compounds possessing multiple bonds have the tendency to polymerize in the presence of an initiator. Polymerization of these compounds can either be affected by the use of chemical initiators such as free radicals …

A Critical Evaluation of Polypropylene Impact Copolymer Morphology
Abstract: In order to improve Polypropylene (PP) impact strength, the process of copolymerizing propylene with ethylene is being used. Polypropylene copolymer is essentially a rubber-toughened material consisting of polypropylene homo-polymer matrix in which ethylene-propylene rubber (EPR) is distributed. The overall impact behavior of the copolymer is solely controlled by the rubber morphology and its distribution in polypropylene matrix, which plays a critical role on crystallinity. Even a similar impact grade polypropylene …
