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 …

Study of PLA and its Synthesis Kinetics
Abstract: In this project we studied about Polylactic Acid and its production kinetics. The most often found optically active hydroxycarboxylic acid is lactic acid (LA, also known as 2-hydroxypropionic acid). In the form of L-and D-Lactic Acid, this chiral molecule may be found. The building blocks of polylactide are carboxylic acid monomers produced by fermentation of sugars from renewable sources, such as sugar cane, beet root, or corn starch. These sugars …
