Abstract (en)
[origin: WO2020228953A1] The invention relates to the use of vinyl acetate isopropenyl acetate copolymers as a low-profile additive (LPA), characterized in that the vinyl acetate isopropenyl acetate copolymers are based on 2 to 98% by weight of vinyl acetate, 2 to 98% by weight of isopropenyl acetate and optionally one or more other ethylenically unsaturated monomers, each relative to the total weight of the vinyl acetate isopropenyl acetate copolymers.
