This paper discusses the various technologies being used to produce
polylactic acids. In addition, attention is drawn to how monomer stereochemistry
can be controlled to impart targeted utility in the final polymers. Specific applications
are described to illustrate further the range of properties that can be
developed by utilising both the basic monomer/polymer chemistries in combination
with post-modification techniques. Finally, the biodegradation mechanism
of polylactic acids will be discussed and contrasted with other biodegradable
polymers. 0 1998 Elsevier Science Limited. All rights reserved
