ABSTRACT:
The invention relates to a new modified polyacrylate comprising fluorinated oxetane (FOX) polymer units functionalized with an unsaturated dicarboxylic acid and siloxane units and to its use as slip- and leveling agent and anti-cratering agent for a variety of applications. Thus, the invention relates to a slip- and leveling agent characterized in that it comprises a copolymer which is obtained by copolymerizing A at least one unit of a fluorinated oxetane polymer functionalized with an unsaturated dicarboxylic acid; B at least one terminal reactive polysiloxane unit; C at least one alkyl(meth)acrylate unit or cycloalkyl(meth)acrylate unit and/or (meth)acrylic acid and/or other units originating from vinylic compounds that can form radicals.
