Abstract
1,169,290. Siloxane-oxyalkylene copolymers. RHONE-POULENCE S.A. 29 Dec., 1967 [30 Dec., 1966], No. 59225/67. Heading C3T. In making polysiloxane-polyoxyalkylene copolymers, a ruthenium carbonyl or 1,3-ketoenolate is used as catalyst for the addition of an alkenyl - polyalkylene - glycolether to Sibonded H of a polysiloxane. Some of the Sibonded H atoms may previously have been reacted with hydroxy-terminated polyalkylene glycol monoether. In examples ruthenium 1:1:1-trifluoroacetylacetonate, trirutheniumdodecacarbonyl or ruthenium acetylacetonate is used to catalyse reaction of α,#-bis-(dihydromethyl silyl) polydimethylsiloxane with the monoallyl ether of polyethylene polyisopropylene glycol or the formate, acetate or monobutyl ether thereof, optionally after partial reaction of the Si-H groups with a monobutyl ether of polyethylene polyisopropylene glycol.
