COPOLYMERIZATION OF ESTERS OF BIS(ALLYLOXYMETHYL) PHOSPHINIC ACID WITH METHYLMETHACRYLATE,
Abstract
A study has been made of the polymerization of bis(allyloxmethyl) phosphinates of a given general formula and copolymerization of these phosphinates with methylmethacrylate (MMA). The study was undertaken because polymers of this type exhibit valuable properties such as enhanced fire resistance or good adhesion to metals. The esters alone did not polymerize, but yielded copolymers with MMA in MMA/phosphorus-containing monomer ratios of 96/4 to 84/16. The copolymers were solid transparent blocks insoluble in the usual solvents of poly(methylmethacrylate). The thermomechanical curves are characteristic of cross-linked systems. Starting mixtures containing over 20 percent organophosphorus monomers yielded rubber-like products. The swelling curves of the polymers in dichloroethane indicated that swelling is accompanied by weight losses as a result of the extraction of low-molecular-weight products from the swollen polymer.
