ABSTRACT

Numerous examples of the copolymerization of 1,6-, or nonconjugated dienes, with vinyl monomers, or co-monomers such as sulphur dioxide, are reported in the literature. In a study of copolymerization of symmetrical nonconjugated dienes with vinyl monomers, a copolymer composition equation was developed and reactivity ratios determined. Cross-linked, water-swellable carboxylic acid copolymers were prepared by copolymerization of acrylic acid in presence of polyallyl tertiary amines. In a study of copolymers of maleic anhydride or its derivatives, radical copolymerization of diallyl fumarate with styrene at 80 in benzene was investigated. The effects of copolymerization conditions on the conversions and viscosities of the copolymers were studied and their structures were characterized by elemental analysis, IR and H NMR spectroscopy. A variety of copolymers and terpolymers of 1,6-diolefins and monovinyl compounds was prepared via radical initiation. Copolymers of vinyl chloride with poly-N-alkyl substituted aminotriazine monomers of small but critical quantities were obtained by free radical initiation.
