Abstract:
There is provided herein a composition comprising a silicone copolymer of the general formula (I) MaMEcDdDEeTfTEgQh where M=R1R2R3SiO1/2; ME=R4R5RESiO1/2; D=R6R7SiO2/2; DE=R8RESiO2/2; T=R9RESiO2/2; T=R9SiO3/2; TE=RESiO2/2; and Q=SiO4/2; where R1, R2, R3, R4, R5, R6, R7, R8, and R9 are each independently selected from the group of monovalent hydrocarbon radicals optionally containing heteroatoms, carbonyl groups, and hydroxyl groups, each independently having from about 1 to about 20 carbon atoms; RE is a monovalent radical defined as: —R10O—(C2H4O)h(C3H6O)i(C4H8O)i—R11 or —R12 with the provision that the copolymer must contain at least one RE group; R10 is a linear or branched divalent hydrocarbon radical containing from 3 to about 10 carbon atoms; R11 is H or —C(═O)CH3 or a monovalent saturated or unsaturated hydrocarbon radical, optionally containing heteroatoms and hydroxyl groups, containing from 1 to about 30 carbon atoms; R12 is a hydrocarbon radical, containing from 2 to about 30 carbon atoms and at least 1 hydroxyl group, optionally containing heteroatoms; subscripts a, b, c, d, e, f, and g are 0 or positive subject to the limitation a+b+c+d+e+f+g
