COPOLYMERIZATION OF MONO-ACRYLOYLETHOXY, DI-ACRYLOYLETHOXY, AND TRI-ACRYLOYLETHOXY FLUOROISOPHTHALONITRILES WITH METHYL-METHACRYLATE, STYRENE, AND DIALLYL PHTHALATE

AF derivatives (AF, 4-acryloylethoxy-2, 5, 6-trifluoroisophthalonitril e; 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 investiga ted. The order of copolymer yields of the AF derivatives with methyl m ethacrylate (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 insolu ble in usual organic solvents.
