Abstract
1404356 Organopolysiloxane emulsions CHEMISCHE FABRIK PFERSEE GmbH 15 Nov 1972 [25 Nov 1971] 52837/72 Heading C3T A stable emulsion of a cross-linkable, highly viscous, hydrolytically stable organopolysiloxane having a viscosity of more than 10,000 cS. at 25 C. is prepared by making an initial emulsion of a solution of the organopolysiloxane in an organic solvent or solvent mixture with at least 150% wt. water and at least 8% wt. of an emulsifier, both calculated on the weight of the polysiloxane, optionally diluting with further water, and then concentrating under reduced pressure, e.g. by distilling at a pressure of 5-30 mm. Hg., or by vacuum steam distillation, at a temperature up to 60 C. to give an emulsion containing 25-45% wt. of the organopolysiloxane. Suitable polysiloxanes are dimethylpolysiloxanes, which may contain up to 10% wt. hydrogen polysiloxane, some of the methyl groups of which may be substituted by phenyl, naphthyl, benzyl, ethylphenyl, trifluoropropyl, cyanopropyl and vinyl groups. The emulsifier can be non-ionic, such as, polyvinyl alcohol or ethylene oxide reaction products of higher fatty acids, fatty alcohols, fatty acid amides and higher amines and salts of the latter with carboxylic or mineral acids; cationic, such as, quaternary ammonium salts; or anionic, such as alkyl and alkylaryl sulphonates and alkyl sulphates. The silicone rubber emulsions can be crosslinked at room or slightly elevated temperatures by incorporating a crosslinker such as hydrogen methylpolysiloxane and a catalyst such as metal carboxylic acid salts. In examples emulsions are prepared from the following polysiloxanes and emulsifiers: (1) dimethylpolysiloxane having terminal OH groups; where R is a straight-chain alkyl group having an average of 16 carbon atoms, x+y=10; (2) a copolymer of dimethylsiloxy units and methylvinyl siloxy units; polyvinyl alcohol; (3) a copolymer of (CH 3 ) 2 SiO and (C 6 H 5 ) 2 SiO units; ethoxylated coconut fatty acid propanolamide or dodecyl benzene-sodium sulphate; (4) an α,#-dihydroxy dimethylpolysiloxane; ethoxylated oleic acid; (5) a copolymer of (CH 3 ) 2 SiO and (C 6 H 5 )(CH 3 )SiO units; ethoxylated (N- stearyl)-trimethylenediamine or octadecyloxymethylpyridinium chloride; (6) dimethylpolysiloxane ; ethoxylated cetyl alcohol. Uses.-In non-crease finishing and in increasing the elastic recovery of textiles; treating paper.
