Abstract

1,1,2,2-Tetramethyl-1,2-disilacyclobutane (TMDSCB), obtained by alkali metal vapor dehalogenation of 1,2-bis(chlorodimethylsilyl)ethane, undergoes room-temperature spontaneous ring-opening copolymerization with styrene (St) and results in a rubbery copolymer (Mw= 1.6 × 105, Mw/Mn = 4.4). In contrast to a thermoplastic homopolymer of TMDSCB (m.p. 110°C) that is obtained by the same procedure in the absence of styrene, the copolymer exhibits two-phase behavior (Tg= -37°C, m.p. 106°C), with the heat of melting being considerably lower in the case of the copolymer (cf. 49.0 and 4.8 Jg-1). Spectral and analytical data are consistent with a copolymer structure, [(Me2SiCH2CH2SiMe2)k (CH2CHPh),]., where k = 3, l = 1 (36%), and k = 6, l = 2 (64%).
