Title:
POLYLACTIC ACID-BASED HIGH MOLECULAR WEIGHT ALIPHATIC COPOLYESTER AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2002293900
Kind Code:
A
Abstract:

To obtain a biodegradable high molecular weight copolyester having practically usable physical properties and formable into a film as well, and to provide a method for producing the copolyester enabling to supply it industrially.

This high molecular weight aliphatic copolyester having weight average molecular weight of ≥40,000 is composed of a repeating unit (P) derived from succinic acid-1,4-butane diol, a repeating unit (Q) derived from - caprolactone and a repeating unit (R) derived from a lactide.
