The invention relates to a polymer having a) a polymer backbone and b) one or more polymeric side chains covalently linked to the polymer backbone, wherein the polymeric side chains comprise a polyether segment and a polysiloxane segment, said polysiloxane segment having a number average molecular weight in the range of 1050 to 6000, and said polyether segment being positioned between the polymer backbone and the polysiloxane segment.

Polymer having polyether and polysiloxane segments

The invention relates to polyisocyanate adducts obtainable by reacting at least one polysiloxane of the structure (I), at least one polyisocyanate having at least three NCO groups, at least one (meth)acrylate of the structure (II), where U is one of the following groups: (III), and optionally a compound reactive with isocyanates. The indices m, n, x and y assume values of 0 to 100. In addition, t=2 to 30, s=1 to 400 and i=1 to 5. The radicals identified by the letter R are suitable organic groups. Ais an OH&#x2014;, NH&#x2014; or COH&#x2014; group. In addition, m+n+x+y&#x2267;3. The invention further relates to a process for preparing the polyisocyanate adducts and to a radiation-curable coating composition comprising at least one radiation-curable polymer as a binder and at least one inventive polyisocyanate adduct. The invention further relates to the use of the inventive polyisocyanate adducts as an additive.
