New Polytetrahydrofuran Graft Copolymers.
Abstract
The discovery that tetrahydrofuran polymerization can be initiated by trifluoromethanesulfonate esters formed in situ from reactive alkyl or polymeric halides and silver trifluoromethanesulfonate has led to this investigation of the synthesis and characterization of a group of novel graft copolymers with potentially interesting and technologically useful combinations of properties. The study has shown that the method is general for heterocycles that will polymerize by cationic ring opening polymerization and that a variety of salts can be substituted for the silver trifluoromethanesulfonate. Properties of the first series of graft copolymers prepared in sufficient quantity for physical testing confirm the expectation that the behavior of the materials produced is related to the chemical structure of the backbone and of the branch, so that copolymers can be tailor-made for specific applications by proper choice of backbone and branch.
