Abstract : The copolymerization of nonconjugated diolefins with vinyl monomers involves departures from conventional vinyl copolymerization kinetics, and the standard forms of the binary or ternary copolymerization composition equations are inadequate. These departures include intramolecular cyclization reactions and generally the formation of some pendent double bonds. A general treatment of the copolymerization of symmetrical nonconjugated diolefins with vinyl monomers gives closed-form relationships which take such reactions and their consequences into account. The general relationships may be approximated by a new series of composition equations which take into account the formation of both cyclized and noncyclized units in the chain and are simple enough for experimental use.
