Abstract
The copolymerization behaviour of 1,3-divinyl-1,1,3,3-tetramethyldisil oxane (DVDS) with styrene in solution, using a free radical initiator, was investigated. Styrene was found to be the more reactive monomer. The FTi.r. and Si-29 n.m.r. spectra indicated that cyclic units were f ormed from DVDS in the copolymer, with five-and six-membered ring stru ctures being common. The cyclocopolymerization mechanisms and the ther mal properties of the cyclocopolymer are reported. (C) 1997 Elsevier S cience Ltd. All rights reserved.
