ABSTRACT:
Silicone polyoxamide and silicone polyoxamide-hydrazide copolymers comprise at least two repeating units of formula IIn this formula, each R1is independently an alkyl, haloalkyl, aralkyl, alkenyl, aryl, or aryl substituted with an alkyl, alkoxy, or halo; each Y is independently an alkylene, aralkylene, or a combination thereof; each G is independently a bond or a divalent residue equal to a diamine of formula R3HN-G-NHR3minus the two —NHR3groups; each R3is independently hydrogen or alkyl or R3taken together with G and with the nitrogen to which they are both attached form a heterocyclic group; each n is independently an integer of 0 to 1500; each p is independently an integer of 1 to 10, and the average of p is 1.2 or greater; and each q is independently an integer of 1 or greater, and every q is not the same integer.
