The Book is designed to provide detailed study of a biodegradable polymer i.e. Poly (lactic acid) PLA. Polymers form the backbone of plastic materials and have various important applications in different areas. PLA is expected to become a commodity polymer (degradable) in a few years period when its price is expected to come down. The book is aimed at students/researchers and Pharmacologists. Key Features: Main focus on core knowledge, facts and materials regarding synthesis and modeling and simulation of poly (lactic acid). Reaction mechanisms are discussed in a simple way so that reader can understand the subject quickly and easily.
