Abstract
There are disclosed crosslinked copolymers of: (1) a bis(hydrocarbyl) vinylphosphonate, particularly bis(beta-chloroethyl) vinylphosphonate; (2) a plyfunctional ethylenicaly unsaturated monomer; and (3) as an optional component one or more monofunctional vinyl comonomers. These crosslinked copolymers may be used, per se, as flame retardant materials or they may be blended with various thermoplastic polymers in order to reduce their flammability.
