    摘要: A novel acrylic-functional organopolysiloxane is proposed which has a plural number of silicon-bonded (meth)acryloxyalkyl groups at each molecular chain end along with one or more of silicon-bonded alkoxy groups. The organopolysiloxane exhibits high curability by the irradiation with ultraviolet light or dual curability either by the ultraviolet irradiation or by the dealcoholation condensation reaction in a moisture-containing atmosphere. The acrylic-functional organopolysiloxane is prepared by the dealcoholation condensation reaction between a starting organopolysiloxane having a plural number of silicon-bonded alkoxy groups at each molecular chain end and a (meth)acryloxyalkyl dimethyl silanol compound in the presence of a specific condensation catalyst which is a divalent tin compound such as tin (II) dioctoate promoting the dealcoholation condensation but suppressing the silanol condensation reaction between the moleculaes of the (meth)acryloxyalkyl dimethyl silanol compound.
