摘要：

Continuous CO2 laser-induced decomposition of 1-methyl-1-vinyl-1-silacyclobutane (MVS) in the presence of energy conveying sulfur hexafluoride provides a highly selective method for production of poly(2-methyl-2-silabuta-1,3-diene) (polysilaisoprene). Trapping with hexafluoroacetone and tetrafluoroethene confirms the intermediacy of 2-methyl-2-silabuta-1,3-diene (silaisoprene), polymerization of which depends on the ratio MVS/SF6. The IR spectrum of the polymer deposited from the gas-phase on to the reactor surface reveals that silaisoprene polymerizes by participation of both double bonds. © 1990.
