The cationic polymerization of octadecyl vinyl ether (ODVE) initiated by trimethylsilyl iodide and 1,l-diethoxyethane in the presence of ZnI, in toluene at 0Β°C and 10Β°C has been investigated. For molecular weights lower than 6000, a linearity of M,, with conversion was observed, but for higher molec

Novel poly(silylenemethylene)s have been prepared by the ring-opening polymerization of 1,3-disilacyclobutanes followed by a protodesilylation reaction with triflic acid. The siliconΒ±aryl bond cleavage could be controlled by using different leaving groups, for instance phenyland para-anisyl substitu
A four-armed star-shaped poly(tetrahydrofuran) (THF) having a pentaerythritol unit at the center of the molecule was synthesized from photoinduced cationic copolymerization of THF and pentaeryithritol tetrakis(3,4-epoxybutanoate) (PETE) in the presence of diphenyliodonium hexafluorophosphate. It was
