Molecular Design of Cationically Polymerizable Monomers and Polymers

摘要

This paper reviews our recent studies on the syntheses of new monomers and polymers that have cationically polymerizable groups such as vinyl ethers,cyclic ethers.A variety of vinyl ether monomers containing silicon or phosphorus atoms were successfully prepared by the regioselective reaction of glycidyl vinyl ether with dichlorosilanes or phosphorus dichlorides.Calixarene derivatives with propargyl,vinyl ether groups were prepared.Calixarene derivatives containing cyclic ethers such as oxirane,oxetane,and spiro orthoesters were also prepared.Polyimides containing propargyl,vinyl ether,and cyclic ether groups aforementioned were successfully prepared using diamines containing the functional groups.Photoinitiated cationic polymerization of the prepared monomers and polymers using suitable photoinitiators in the film state proceeded efficiently to produce crosslinked films.Behaviors of photoinitiated cationic polymerizations of the materials are also described.
