Abstract: The invention relates to a process for preparing oligo- or polyalkylene ether-modified polysiloxanes by transesterification of alkoxy-functionalized polysiloxanes with OH-terminated oligo- or polyalkylene ethers in the presence of an alkanesulfonic acid as catalyst. Oligo- or polyalkylene ether-modified polydimethylsiloxanes obtainable through this process are suitable as defoamers, as wetting agents, and as additives in coating material formulations.

Abstract: The invention relates to a process for preparing oligo- or polyalkylene ether-modified polysiloxanes by transesterification of alkoxy-functionalized polysiloxanes with OH— terminated oligo- or polyalkylene ethers in the presence of the tetra-n-C1-C6-alkoxy- titanate as catalyst. Oligo- or polyalkylene ether-modified polydimethylsiloxanes obtainable through this process are suitable as defoamers, as wetting agents, and as additives in coating material formulations.

Abstract: The present invention relates to novel block copolymers of general formula (I). The invention further relates to a method for producing such block copolymers and to the use of such block copolymers, particularly as additives in liquid coating-agent compositions. A{X—[O—C(O)NH—Y—NH—C(O)—O-M-B]k}n (I). In formula (I), the variables have the following meanings: n is a number in the range from 1 to 40 or 2 to 40, particularly 1 to 10 or 2 to 10 and especially 2 to 5; k is 1 or 2; A is a poly(dimethylsiloxane) block; B is a polymer block constructed of ethylenically unsaturated monomers, which optionally comprises a terminal group different from hydrogen; X is a bivalent or trivalent group having 2 to 20 C atoms, which is saturated or unsaturated and which optionally bears 1, 2, 3, or 4 substituents selected from among OH, COOH, CONH2, C1-C4 alkoxy, C1-C4 alkoxycarbonyl, and halogen; Y is a bivalent hydrocarbon group having 2 to 20 C atoms, which is saturated or unsaturated, and M is a chemical bond or C2-C10 alkylene, which can be interrupted by one or two groups not directly adjacent, selected from among O, C(═O)O, and (C═O)NH and which optionally bears 1, 2, 3, or 4 substituents selected from among OH, COOH, CONH2, C1-C4 alkoxy, C1-C4 alkoxycarbonyl, and phenyl.
