  • Related Publications
Polylactides are aliphatic polyesters derived from lactic acid, and various derivatives thereof, and are one of the most promising of polymers based on starting materials available from renewable resources. Materials based on these polymers are at the cutting edge of progress in sustainable materials science.

This book provides an overview of the latest developments in a number of aspects of polylactide research. Chapters cover synthesis using novel catalysts and modified monomers, new copolymers, blends of polylactides with other polymers, stereocomplexes and nanocomposites. The information contained therein will be of interest to all involved in the development of polylactides and other polymers based on sustainable resources, with discussions on how to modify and improve these materials to expand their capabilities even further.
