SYNTHESIS OF POLYESTER-POLYETHER MULTIBLOCK COPOLYMERS FROM POLYESTERS

Received Date: 31 August 1984

A polymeric method was explored for the preparation of polyester-polyether multiblock copoly-mers using polyesters and polpethers as starting materials. The mechanism of the reaction and theeffect of the segment structure on it, the segment sequence of the block copolymers prepared havebeen studied. It has been shown that to the polymeric method the degree of compatibility betweenstarting polyester and polyether is of paramount importance, which determines not only the com-positional homogeneity of the block copolymers formed but also the success of the polymeric method to get the block copolymers of the expected structure.
