Abstract

A composition for rendering cellulosic fibrous sheet material non-adherent to normally adhesive materials, comprises an aqueous emulsion of a liquid methyl-hydrogenpolysiloxane of the formula <FORM:0693788/IV (a)/1> in which a is 1 to 1.5, b is 0.75 to 1.25, and a+b is 2.0 to 2.25, in an aqueous solution of a water-soluble cellulose ether, the emulsion containing 0.1 to 20 per cent by weight of the polysiloxane and 0.1 to 10 per cent by weight of the ether. The polysiloxanes employed may be cyclic or linear and may contain traces of hydroxy radicals. The linear polymers may be end-blocked, e.g. with trimethylsiloxy or dimethylhydrogensiloxy units. Cellulose ethers specified are methyl-and hydroxyphenyl-celluloses and the sodium salt of carboxymethyl cellulose (the glycollic acid ether of cellulose). Emulsifying agents may be used in making the emulsions, preferably quarternary ammonium salts or higher aliphatic alcohol sulphates. The polysiloxanes may be stabilized by adding an organic acid such as acetic acid. Catalysts may be added to the emulsions, e.g. octoates, hexoates, acetates, oleates, stearates, naphthenates, laurates and resinates of lead, iron, zinc, copper, aluminium, magnesium, cadmium, cobalt, nickel and sodium, and sodium bicarbonate and aluminate. The emulsions may be applied to all types of paper and paperboard and textile fabrics, by wetting the material therewith and drying and curing the wetted material, preferably at 40 DEG to 200 DEG C. The treated materials may be used (1) for making containers into which hot asphalt or polymers such as polyisobutylene may be poured and solidified, (2) in contact with the adhesive surfaces of pressure-sensitive tapes, (3) for preventing sheets of rubber from adhering together, and (4) in lining boxes of partially baked bread goods. In examples, aqueous emulsions of (A) a trimethysiloxy-end-blocked methylhydrogen polysiloxane and (B) zinc 2-ethyl hexoate catalyst, were made with the aid of a higher aliphatic alcohol sulphate. Portions of A and B were added to aqueous solutions of different cellulose ethers and the resulting emulsions were used to treat kraft paper and paperboard.
