Divinyloxy monomers have been copolymerized with vinyl chloride and vinyl acetate by free radicals to yield crosslinked gels. Cationic copolymerization with alpha -methyl styrene, initiated by stannic chloride, also gave cross-linked products, although soluble polymers were obtained from the copolymerization of styrene with the monovinyl ether of diethylene glycol. This paper presents results of an experimental study which demonstrated that copolymerization of 1,4-divinyloxy-butane (DVOB) or diethylene glycol divinyl ether (DGDE) with butyl vinyl ether led to soluble copolymers when iodine was used as initiator. Further investigation showed that both DVOB and DGDE are homopolymerized by iodine to yield soluble saturated polymers. IR and NMR spectroscopy was employed to characterize copolymers synthesized.
