    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.

    摘要: A novel method is proposed for the synthesis of an organopolysiloxane having two hydrogen atoms directly bonded to the same silicon atom at the molecular chain end. The method comprises mixing a dihydro isopropenyloxy silane with an organosilicon compound having at least one silanolic hydroxy group so that a condensation reaction takes place between the isopropenyloxy group of the former reactant and the silanol group of the latter reactant forming acetone as a by-product. The method is advantageous in respect of the absence of any acidic or basic by-product contained in the product as an impurity in the conventional methods.

    摘要: The invention provides a novel room temperature-curable organopolysiloxane composition useful as an adhesive or a sealing material with remarkably extended workable time owing to the delayed surface filming. The base component in the composition is a conventional diorganopolysiloxane terminated with hydroxy groups at both molecular chain ends admixed with several known ingredients such as a cross linking agent, curing catalyst, filler and the like. The most characteristic ingredient in the composition effective to achieve the above mentioned desired property is a 1,1,1-trimethyl-3-hydrocarbyl-3,3-di(acylamino)disiloxane which belongs to a novel class of organopolysiloxane compounds and method is described for the preparation of these siloxane compounds.
