Title:
METHOD FOR PREPARATION OF BLOCK COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2020/197147
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a block copolymer, the method comprising a step of ring-opening polymerizing lactide monomers in the presence of a poly(3-hydroxypropionate) initiator to prepare a polylactide-poly(3-hydroxypropionate) block copolymer.
