    • 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.
    • 本发明涉及用于制备增塑溶胶的粉状核/壳聚合物,其具有惊人的低吸水性。 本发明还涉及由这些聚合物制备并且同样具有低吸水性并且另外具有良好的储存稳定性,良好的机械性能和良好的增塑剂相容性的增塑溶胶浆料。 核/壳聚合物由初级粒度为至少250nm的胶乳颗粒组成,核心由甲基丙烯酸甲酯,具有C 2至C 8的(甲基)丙烯酸酯或芳族醇基团和任选的其它单体组成, )除了这些组分外,还包含(甲基)丙烯酸和/或胺取代的(甲基)丙烯酸烷基酯的酰胺。

    • Grafted triglycerides comprising an acrylated triglyceride grafted with a fatty acid residue containing 4 to 28 carbon atoms. Also described are methods for making a grafted triglyceride and for curing a material selected from vinyl esters and unsaturated polyesters and mixtures thereof and optionally a reactive diluent. The method includes the steps of mixing a grafted triglyceride of the present invention with a material selected from vinyl esters, unsaturated polyesters and mixtures thereof to form a mixture, and curing the mixture to form a cured resin system. A cured resin system comprising a cured product obtained by the foregoing method and composites containing the cured product and a filler or reinforcing material are also disclosed. This method also includes use of the grafted triglycerides to make toughened resin and composite systems with reduced hazardous air pollutants without significantly reducing the glass transition temperature and significantly increasing the viscosity.
