Abstract
A new catalyst system comprising a combination of dicobalt octacarbonyl and a hydridosilane has been successfully employed for the tandem isomerization and cationic copolymerization of 1-allyloxy-2-phenoxyethane (M1) and l-allyloxyoctane (M2). Reactivity ratios of r1 = r2 = 0.58 ± 0.01 were calculated for these monomers by both the Mayo-Lewis and the Fineman-Ross methods which are indicative of a statistical copolymerization. A GPC study of the copolymerization showed that only copolymers were obtained. This data further indicates that the isomerization of the individual monomers and their subsequent copolymerization proceed at very nearly identical rates. The copolymerization of allyl ether monomers presents an opportunity for designing novel polymers with tailored properties.
