A siloxane polymer comprising:
- (a) one or more segments of formula (I):
- and
- (b) one or more segments of formula (II):
- wherein:
- each R1, R2, R3, and R4 is independently a hydrogen atom, a C1-14 hydrocarbyl group, or a
- C1-14 hydrocarbyloxy group;
- each X1 and X2 is independently an oxygen atom, a sulfur atom, >NH, or >N(C1-6alkyl);
- each G1 and G2 is independently a C1-14 hydrocarbylene group;
- each G3 is independently a C1-14 hydrocarbylene group, which is optionally substituted one or more times by substituents selected from the group consisting of —OH and —O(C1-6alkyl);
- and
- each k is independently an integer ranging from 5 to 5000.
