A siloxane polymer of formula (I):
- wherein:
- each R′, R2, R3, and R4 is independently a hydrogen atom, a C1-14 hydrocarbyl group, or a C1-14 hydrocarbyloxy group;
- Rx and Ry are —(CH2)nC(═O)—R5;
- each R5 is independently —O—R6;
- wherein each R6 is independently C1-12 alkyl, which is substituted by one or more —OH groups, wherein any two —OH substituents on immediately adjacent carbon atoms may optionally combine to form an epoxy group;
- each n is independently an integer ranging from 9 to 17;
- and
- k is independently an integer ranging from 5 to 5000.
