The invention relates to a polymer comprising a) at least two polymer backbone chains and b) at least one polymeric connecting chain comprising at least two polyether segments and one polysiloxane segment, said polysiloxane segment having a number average molecular weight in the range of 400 to 6000 g/mol, and at least one of the at least two polyether segments being positioned between the polymer backbone chains and the polysiloxane segment, wherein the at least two polymer backbone chains are linked by the at least one polymeric connection chain.

Ladder copolymer

The invention relates to the use of a polysiloxane having a plurality of siloxane groups and at least one tertiary amide group covalently linked as a pending and/or terminal group to the polysiloxane, as a defoaming agent in a liquid composition.
