Zusammenfassung
(EN)
The invention relates to pulverulent core/shell polymers for the preparation of a plastisol, which have surprisingly low water absorption. The invention further relates to the plastisol pastes which are prepared from these polymers and likewise have low water absorption and additionally possess good storage stability, good mechanical properties and good plasticizer compatibility. The core/shell polymers consist of latex particles having a primary particle size of at least 250 nm, the core consisting of methyl methacrylate, (meth)acrylic esters with C2 to C8 or aromatic alcohol radicals and optionally further monomers, and the shells(s) comprising, in addition to these components, also amides of (meth)acrylic acid and/or amine-substituted alkyl esters of (meth)acrylic acid.
