<p>The invention relates to novel carboxylic acid-functional polysiloxane polymers having at least one unit of the formula <CHEM> in which R is a monovalent hydrocarbon radical, A is a carboxylic acid-functional radical selected from the group consisting of <CHEM> wherein R min is a divalent hydrocarbon radical selected from the group consisting of (CH2)y, CH=CH, C14H26 or a cyclic hydrocarbon radical selected from the group consisting of C3H4, C4H6, C5H8, C6H4, C6H6, C6H8, C6H10 and C10H6, or a bicyclic radical selected from the group consisting of C7H8, C7H10, C8H10 and C8H13, R sec is selected from the group consisting of saturated divalent hydrocarbon radicals, hydrocarbonoxy radicals in which the hydrocarbon group is linked to the silicon by a carbon bond and the oxygen is in the form of an ether linkage and unsaturated divalent hydrocarbon radicals, a is a number of from 0 to 2, b is a number of from 0 to 10, and y is a number of from 0 to 10.</p> |
