## Abstract A novel PLA‐based polymer containing reactive pendent ketone or hydroxyl groups was synthesized by the copolymerization of L‐lactide with __ε__‐caprolactone‐based monomers. The polymer was activated with NPC, resulting in an amine‐reactive polymer which was then cast into thin polymeric
Methylenediphenyl diisocyanate (MDI) was used as the chain extender for low molecular weight poly(lactic acid) (PLA) to produce high molecular weight biodegradable polymer material with a better heat resistance. PLA prepolymer with a number-average molecular weight (M n ) of 5800 and a weight-averag
