Abstract:
A composition liquid at room temperature, consisting of the reaction product of,(1) a polymer component selected from the group consisting of(A1) polyorganosiloxanes comprising units (T units) of the formula (R.sub.1 Si--O.sub.3/2) and optionally, units (M units) of the formula (R.sub.3 Si--O.sub.1/2),(A2) polyorganosiloxanes comprising units (Q units) of the formula (Si--O.sub.4/2) and, optionally, units (M units) of the formula (R.sub.3 Si--O.sub.1/2),and mixtures thereof in whichR is identical or different and represents non-halogenated hydrocarbon radicals having 1 to 18 carbon atom(s) per radical or OR.sup.1, whereR.sup.1 is identical or different and represents hydrogen or a monovalent, unsubstituted or substituted hydrocarbon radical having 1 to 8 carbon atom(s), with the proviso that A1 and A2 contain from 0.01% to 3.0% by weight, of Si-bonded radicals OR.sup.1, andoptionally one or more of (B) through (J):(B) vinyl chloride-hydroxypropyl acrylate copolymers,(C) vinyl acetate-ethylene copolymer,(D) polyvinyl chloride(E) polyamide,(F) polyester,(G) acrylate-polyester copolymers,(H) polyamide-polyester copolymers,(I) vinyl acetate-polyester copolymer, and(J) monomeric (meth)acrylates, with the proviso that they are copolymerized with Si-bonded (meth)acrylate group-containing silanes,(2) a silane of the formula R.sup.3.sub.x Si(OR.sup.2).sub.4-x, whereR.sup.2 is a monovalent, unsubstituted or substituted hydrocarbon radical,R.sup.3 is a monovalent, substituted or unsubstituted alkyl, alkenyl, or cycloalkyl radical,x represents 0 or 1,(3) from about 10% to 90% by weight based on the total weight of the composition of one or more organic solvents,(4) optionally, a catalyst and(5) optionally, water,wherein polyorganosiloxane (A1) contains M units and wherein the ratio of M units to T units is from about 0.1:1 to about 1.2:1; andwherein polyorganosiloxane (A2) contains M units and wherein the ratio of M units to Q units is from about 0.01:1 to about 2.1:1.
