Copolymerization of Mono-, Di-, and Tri-acryloylethoxy Fluoroisophthalonitriles with Methyl Methacrylate, Styrene, and Diallyl Phthalate

Abstract

AF derivatives (AF, 4-acryloylethoxy-2, 5, 6-trifluoroisophthalonitrile; DAF, 4, 6-diacryloylethoxy-2, 5-difluoroisophthalonitrile, and TAF, 2, 4, 6-triacryloylethoxy-5-fluoroisophthalonitrile) were synthesized from tetrafluoroisophthalonitrile, and radical homopolymerizations or copolymerizations of these monomers with vinyl monomers were investigated. The order of copolymer yields of the AF derivatives with methyl methacrylate (MMA) or styrene (St) was TAF>DAF>AF . The copolymer yield of AF with diallyl isophthalate (DAIP) or diallyl terephthalate (DATP) was larger than homopolymer yield of DAIP or DATP. The copolymers of DAF or TAF with diallyl phthalate (DAP) were heat-resistant and insoluble in usual organic solvents.
