Poly(glutamic acid) (PGA) is a biocompatible and biodegradable polymer which can be conjugated through side chain condensation with any suitable molecule. Due to a controlled proprietary and patented process with living polymerization technology a superior quality of PGA is achieved. Usual poly amino acids carry significant amounts of cyclic structures, carbamates or isocyanates. Through a very well controlled polymerization process, well defined terminal groups and polymeric structures are achieved in high purity and with superior polydispersity.
