<p>Provided are alkenylphosphorus compound polymers and alkenylphosphorus compound copolymers which overcome the problems associated with conventional flame retardants, and which also exhibit a characteristic of being rarely discolored even when heated. Also provided are alkenylphosphorus compounds suitable as starting monomers for the polymers and copolymers. The akenylphosphorus compound polymers are represented by general formula (2). The alkenylphosphorus compound copolymers are copolymers obtained by copolymerizing an alkenylphosphorus compound represented by general formula (1) with an alkene compound represented by general formula (3).</p> |
