摘要： A process for the solventless polymerization of brominated styrenes includes blending monomers of brominated styrenes with a polymerization initiator, feeding the monomer/polymerization initiator mix into a prepolymerizer wherein the monomers begin to polymerize, and feeding the monomer/polymerization initiator mix and the partially polymerized bromostyrene into a screw-type extruder to drive the polymerization to a high degree of completion in a short period of time. Optionally, the monomers may be preheated before mixing with the initiator, or a heater may be included in the prepolymerizer.

摘要： Antimony free flame retardant compositions are prepared by combining a polymer resin, certain halogenated polyphenylene ether flame retardants and a non-brominated phenoxy oligomer or polymer such as a poly-phenylene ether, aryloxyester, or aryloxycarbonate. The present antimony free flame retardant compositions also typically have more desirable physical properties than similar compositions comprising antimony trioxide and other flame retardant. In particular embodiments, ATO free flame retardant HIPS and PC/ABS compositions are provided.
