Abstract: This invention relates to a radiation curable silicone compositions. More particularly this invention relates to radiation curable silicone compositions comprising a vinyl ether functional silicon compound, a cationic photoinitiator, a free radical photoinitiator, and dodecylphenol. The compositions of this invention can further comprise a vinyl ether compound which is free of silicon atoms. The radiation curable silicone compositions of this invention are useful as release coating compositions which are especially suitable for release of pressure sensitive adhesives.

Abstract: The invention is a process for making high molecular weight polymers of monoalkenyl arene monomers comprising:1) copolymerizing vinylbenzocyclobutene with the monoalkenyl arene monomer through the vinyl moiety;2) submitting the thus formed copolymer to conditions sufficient to open the side rings of the benzocyclobutene moieties;wherein the amount of vinylbenzocyclobutene in the copolymer is such that the polymer formed by step 2) does not reach a gel point. Such copolymers allow the building of molecular weight after the initial polymerization.
