Abstract
The present invention has an object to provide a flame retardant excellent in heat resistance and hard to cause juicing or mold deposits in molding. A flame retardant relating to the present invention has a feature to be made of a polymer constituted of at least one kind, as a building block, among phosphazene compounds each having, in a molecule thereof, at least one of one kind of polymerizable functional group selected from the group consisting of a vinyl group, an allyl group, an acryloyloxy group, a methacryloyloxy group, an acryloyl group, and a methacryloyl group.
Claims14
A flame retardant comprising a polymer constituted of at least one type, as a structure unit, of phosphazene compounds, each having per molecule at least one polymerizable functional group selected from among a vinyl group, an allyl group, an acryloyloxy group, a methacryloyloxy group, an acryloyl group, and a methacryloyl group.
A flame retardant comprising a polymer constituted of at least one type, as a structure unit, of phosphazene compounds, each having per molecule at least one of an acryloyloxy group-substituted phenyl group, an acryloyloxyalkyl group-substituted phenyl group, a methacryloyloxy group-substituted phenyl group and a methacryloyloxyalkyl group-substituted phenyl group, in which the number of repeat units are 3 to 15.
A flame-retardant resin composition characterized by admixing at least one of polymers each comprising, as a structure unit, a phosphazene compound having a polymerizable functional group with a resin.
A flame-retardant resin composition characterized by admixing at least one of polymers each comprising, as a structure unit, a phosphazene compound having a polymerizable functional group selected from among a vinyl group, an allyl group, an acryloyloxy group, a methacryloyloxy group, an acryloyl group, and a methacryloyl group with a resin.
