Preparation of polyvalent metal salts of ethyleneglycol–methacrylate–maleate (EMM) was investigated by the reaction of Na salt of EMM and chlorides of polyvalent metals such as Al 3+ , Cr 3+ , Fe 3+ , Ni 2+ , Co 2− , and Cu 2+ . It was found that, among the metal salts obtained, the Cr salt could be obtained in the form of (EMM) 2 Cr(OH) in high purity, where EMM means EMM residue,Then, (EMM) 2 Cr(OH) was copolymerized with styrene, MMA, and hydroxyethyl methacrylate. In the copolymerization, the rates of copolymerization increased markedly as the concentration of (EMM) 2 Cr(OH) increased. As for the physical properties of the copolymers obtained, Rockwell hardness and compressive strength can be improved by introducing (EMM) 2 Cr(OH) into the polymers, and HDT, tensile, and flexural strengths can also be improved by selecting the most suitable concentration of (EMM) 2 Cr(OH) according to the species of vinyl monomer. Further, TGA and boiling water resistance of the copolymers are also discussed.
