Alternating radical copolymerization of phenylacetylene with cyclooligoarsines

摘要

To develop new polymerization methods for heteroatom-containing unsaturated polymers is of considerable interest because such polymers show unusual properties. Among various types of such polymers, the simplest one is heteroatom-containing polyvinylenes, of which properties might be attractive. However, no example of these polymers has been reported except poly(vinylene-sulfide), because of synthetic difficulties. In this report, we describe a synthesis of poly(vinylene-arsine)s by a radical alternating copolymerization of phenylacetylene and cyclooligoarsines.
