Abstract
Abstract Copolymerization of methyl 2-cyano-3-phenyl-2-propenoate (MCP) and 2-phenyl-1,1-dicyanoethene (PDE) with ethyl, n-butyl, i-butyl, 2-chloroethyl, and phenyl vinyl ethers in broad ranges of comonomer ratios always produces copolymers of an equimolar composition. The alternating structure of these copolymers was established by elemental analysis and by infrared, 1H− and 13C-NMR spectroscopy. Microstructure analysis of the copolymer of PDE and phenyl vinyl ether, as deduced from 1H and NOESY 13C-NMR data, demonstrated the formation of alternating monomer structures with different orientations of the monomer units. Additional characterization of the copolymers was carried out by DSC and TGA. The order of decreasing T g values, ethyl > phenyl > 2-chloroethyl >i-butyl >n-butyl vinyl ether, is the same for both MCP and PDE.
