19th International Congress of Chemical and Process Engineering, CHISA 2010 and 7th European Congress of Chemical Engineering, ECCE-7, Prague, Çek Cumhuriyeti, 28 Ağustos - 01 Eylül 2010, (Tam Metin Bildiri)
Plastics are used in industrial and commercial applications. In today's world of green chemistry and concern for the environment, polylactic acid (PLA) has additional drivers that make it unique in the market place. The starting material for the final polymer, lactic acid, can be made by a fermentation process using 100% annually renewable resources. The polymer will also rapidly degrade in the environment and the by-products are of very low toxicity, eventually being converted to CO 2 and water. Lactic acid can be obtained from renewable sources like corn, potato, whey, and sugar cane. PLA, is produced via polymerization of lactic acid, which is biocompatible and biodegradable polyester. The effects of catalyst type on the molecular weight of polylactic acid, which was produced by melt polycondensation method, are elucidated. This is an abstract of a paper presented at the 7th European Congress of Chemical Engineering-7 and 19th International Congress of Chemical and Process Engineering CHISA (Prague, Czech Republic 8/28/2010-9/1/2010).
