Process for producing a polymer

Abstract

A novel polymer is produced by a novel polymerization or copolymerization process in the presence of a free radical-forming catalyst or radical-forming irradiation energy to provide a monomer of the general formula CH/sub 2/=C(R/sub 1/)(COO)-(R/sub 2/OOCR/sub 3/COO)sub(n)-R/sub 2/OH wherein R/sub 1/ is hydrogen, halogen or alkyl radical containing one or two atoms; R/sub 2/ is an epoxy compound residue; R/sub 3/ is a polybasic anhydride residue; and n is an integer. This polymer: (1) enables the cross-linking reaction, (2) improves the adhesiveness of adhesives, pigments, films and coatings; (3) is adjustable for mutual solubility and affinity when blending with other solvents and resins; (4) is resistant to yellowing and mechanically stronger than the benzene nucleus of styrene; (5) improves the textile dyeing affinity, adhesiveness and dispersion of pigments, and the dimensional stability of films and sheets; (6) is suitable as a molding material of synthetic resins, adhesives and coatings because of its three dimensional cross-linking construction; (7) can control the hardness, flexibility and rigidity of the molding materials; and (8) can lower the cost of production. In an example, 10 g of the monomer of the above mentioned formula wherein n=1, R/sub 1/=CH/sub 3/, R/sub 2/=-(CH/sub 2/)/sub 2/ and R/sub  More>>

Next the contents are precipitated in a large amount of benzene to produce a polymer having a molecular weight of 9,500. The products have good dimensional stability as molding materials.}
