    • The present invention relates to a (meth)acrylate polymer for preparing a coating composition, where the (meth)acrylate polymer has a weight-average molecular weight in the range from 10 000 to 60 000 g/mol and the (meth)acrylate polymer comprises 0.5 to 40% by weight of units derived from (meth)acrylic monomers which in the alkyl radical have at least one double bond and 8 to 40 carbon atoms, 0.1 to 10% by weight of units derived from monomers containing acid groups, and 50 to 99.4% by weight of units derived from (meth)acrylates having 1 to 12 carbon atoms in the alkyl radical that have no double bonds or heteroatoms in the alkyl radical, and these (meth)acrylates having 1 to 12 carbon atoms in the alkyl radical are selected such that a polymer composed of these (meth)acrylates having 1 to 12 carbon atoms in the alkyl radical has a glass transition temperature of at least 40° C., based in each case on the weight of the (meth)acrylate polymer.The present invention further relates to a coating material comprising the stated polymer, and to a method of producing a coating. The present invention additionally describes a coated article comprising a coating obtainable by the method.
    • 本发明涉及一种用于制备涂料组合物的(甲基)丙烯酸酯聚合物,其中(甲基)丙烯酸酯聚合物的重均分子量在10000至60000g / mol范围内,(甲基)丙烯酸酯聚合物 包含0.5至40重量%的衍生自(甲基)丙烯酸单体的单元,其在烷基中具有至少一个双键和8至40个碳原子,0.1至10重量%的源自含酸基团的单元,以及 50〜99.4重量%的衍生自在烷基中不具有双键或杂原子的烷基中具有1至12个碳原子的(甲基)丙烯酸酯的单元,并且这些在(甲基)丙烯酸烷基酯中具有1至12个碳原子的(甲基)丙烯酸酯 选择烷基,使得由烷基中具有1至12个碳原子的(甲基)丙烯酸酯组成的聚合物的玻璃化转变温度至少为40℃,基于每种情况下的(甲基) 丙烯酸酯聚合物。 本发明还涉及包含所述聚合物的涂料,以及制备涂料的方法。 本发明另外描述了包含可通过该方法获得的涂层的涂覆制品。
