Abstract
The invention relates to a bi-functionalized polysiloxane brush copolymer comprising at least one hydroxyl-terminated polyalkyleneglycol side chain and at least one onium-functionalized side chain as defined herein, and a method for preparing the bi-functionalized polysiloxane brush copolymer, a curable composition comprising the bi-functionalized polysiloxane brush copolymer and its use.
Claims15
A bi-functionalized polysiloxane brush copolymer, comprising:
- at least one hydroxyl-terminated polyalkyleneglycol side chain —[—S—B];
- and
- at least one onium-functionalized side chain -[T-C],
- wherein:
- B represents hydroxyl-terminated polyalkyleneglycol side chain;
- S is a linker group wherein the moiety Si—C—C— of which said Si is a part of the polysiloxane backbone;
- C represents an onium-functionalized side chain;
- T is a linker group wherein the moiety of Si-heteroatom-C— of which said Si is a part of the polysiloxane backbone.
