Abstract: The presently claimed invention is directed to a copolymer obtained by reacting at least one isocyanate (A) comprising at least one allophanate group and at least one active double bond with at least one isocyanate reactive component (B) to form an intermediate product (C); and reacting the intermediate product (C) with at least one active double bond reactive component (D) to obtain the copolymer which can be used as dispersant. The at least one isocyanate reactive component (B) is selected from the group consisting of monofunctional polyether amine (B1), monofunctional polyether alcohol (B2), C6-C30 monofunctional alcohol (B3) and monofunctional polyester alcohol (B4).

Abstract: Disclosed is a process of making silicone-in-water emulsion, compositions including a silicone-in-water emulsion and use of the compositions as an additive in paint and coating formulations, printing ink compositions, personal care products, textiles, leather and indirect food contact applications. The process includes contacting a silicone with an organic non-polar solvent, adding an anionic surfactant, and further adding water under shear, to obtain a silicone-in-water emulsion; and removing the non-polar solvent, wherein the silicone-in-water emulsion has a particle size distribution Dv50 in the range from ≥0.1 μm to ≤25 μm, determined according to dynamic light scattering technique with a fixed scattering angle of 90°.

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.
