摘要

Vinyl ether terminated polyurethane (VEPU) was synthesized in this investigation. The copolymerization behavior of VE-PU and dimethyl maleate (DMA) was investigated by C-13-NMR. It was found that the copolymerization of VE-PU and DMA is of alternating composition, and no homopolymer structure was found in the polymerization products. Differential photocalorimetry results show that, when the monomer feed molar ratio was close to 1 : 1, the total conversion increased, whereas the effective conversion decreased. The rate of copolymerization was affected by oxygen and reaction temperature and depended on the square root of both the initiator concentration and the light intensity. The rheological properties of VEPU/DMA system were also studied. (c) 2005 Wiley Periodicals, Inc.
