Abstract
Three new kinds of alternating copolymers were successfully synthesized from 1,3-cyclooctadiene and acrylic monomers complexed with organoaluminum compounds. The copolymerization rate is as follows; acrylonitrile>methacrylonitrile>cis-crotononitrile. As an optimum condition giving the alternating copolymer, equimolar amounts of acrylonitrile, 1,3-cyclooctadiene, and EtAlCl2 as a catalyst were used. The intrinsic viscosity of copolymers is from 0.40—0.60 dl/g. From their 1H NMR and infrared spectra the preferential 1,4-addition and cis-structure of carbon—carbon double bond of cyclooctadiene unit were confirmed.
