METHOD OF PRODUCING STAR-LIKE POLYMERS Russian patent published in 2016 - IPC C08G63/08 C08G63/82 

Abstract RU 2589876 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing star-like polymers based on lactide monomer and glycolide monomer or lactide monomer. described is a method of producing star-like polymers based on lactide monomer and glycolide monomer or lactide monomer by opening cycle in presence of catalyst, wherein catalyst has formula ,

where R denotes a (C1-C6)haloalkyl; initiator is a polyatomic alcohol, containing from 3 to 6 hydroxyl functional groups.

EFFECT: obtaining low-molecular polymers with full functional activity of beam.
