Abstract
AbstractChain transfer constants (Cs) for a number of substrates containing the silicon‐oxygen bond are measured in polymerizing methyl methacrylate. Additionally, a few measurements are run in styrene in order to estimate the influence of polar factors on chain transfer. The methylsiloxanes studied all show very low values of Cs (10−5 to 10−6). The chain transfer constants of a number of propylsiloxane derivatives are negligibly influenced by the presence of silicon. Thus, (Me3SiO)2MeSiCH2MeCH(C6H5) shows a value of Cs nearly that reported for cumene, and (MeO)3SiCH2CH2CH2SH shows values of Cs close to those reported for alkyl mercaptans.
