Abstract
A polyorganosiloxane comprising at least one organofunctional group per molecule having multiple hydrolyzable groups. The organofunctional group is described by formula --Z.sub.b --R.sup.4 (Z--SiR.sup.2.sub.n X.sub.3-n).sub.a, where each R.sup.2 is an independently selected monovalent hydrocarbon radical comprising 1 to about 18 carbon atoms; each Z is independently selected from the group consisting of divalent hydrocarbon radicals comprising about 2 to 18 carbon atoms and a combination of divalent hydrocarbon radicals and siloxane segments; R.sup.4 is independently selected from the group consisting of a silicon atom and a siloxane radical comprising at least two silicon atoms and each Z is bonded to a silicon atom of R.sup.4 with the remaining valences of the silicon atoms of R.sup.4 being bonded to a hydrogen atom, a monovalent hydrocarbon radical comprising 1 to about 18 carbon atoms, or forming siloxane bonds; each X is independently selected from the group consisting of halogen, alkoxy, acyloxy, and ketoximo; n is 0, 1, or 2; a is at least 2; and b is 0 or 1, provided, when b is 0, R.sup.4 is bonded to the polyorganosiloxane through a siloxane bond.
