A defoamer composition contains a compound based on polybutadiene having at least one repeat unit selected from the divalent radicals:

Defoamer composition based on organofunctionally modified polybutadienes

A process can be used for preparing polyether-modified polybutadienes. The process involves reacting at least one polybutadiene (A) with at least one epoxidizing reagent (B) to give at least one epoxy-functional polybutadiene (C). The at least one epoxy-functional polybutadiene (C) is then reacted with at least one hydroxy-functional compound (D) to give at least one hydroxy-functional polybutadiene (E). The at least one hydroxy-functional polybutadiene (E) is finally reacted with at least one epoxy-functional compound (F) to give at least one polyether-modified polybutadiene (G).

Polyether-modified polybutadienes and processes for preparation thereof

Compounds are based on polyether-modified polybutadiene, where the polyether-modified polybutadiene contains repeat units selected from the divalent radicals: The radical B has at least one ester group.

Polyester-polyether-modified polybutadienes and processes for preparation thereof

A defoamer composition based on organofunctionally modified polysiloxanes contains one or more laterally polyether-modified polysiloxanes as component A and at least one terminally polyether-modified polysiloxane as component B.
