    • The invention relates to a method for the production of a contact adhesive material based on acrylates, characterised in that a) firstly, (co-) polymers are produced by free radical polymerisation from the following monomers: i) a mixture of acrylic monomers, or of acrylic and vinylic monomers, ii) monomers, which contain vinyl groups and with at least one other functional group which is unreactive with relation to radical polymerisations and which is chosen such that it may participate in polymerisation-like reactions with isocyanate groups, making up from 0.1 to 25 wt. % of the monomer mixture, b) by means of a further reaction under addition of isocyanatoethyl acrylate and/or isocyanatoethyl methacrylate, double bonds are introduced along the polymer chain and c) a cross-linking of the polymers is achieved by means of irradiation with energetic radiation after the reaction between the functional groups and the isocyanate groups.
    • 基于丙烯酸酯用于制备压敏粘合剂的方法,其特征在于:a)初始(通过自由基聚合共)从下列单体制备的聚合物:i)所述单体的丙烯酸类单体的或丙烯酸和乙烯单体ii)含有乙烯基的混合物,其中各 至少一个以上的自由基聚合反应性的官能团,其中所述官能团被选择为使得它们能够进入与异氰酸酯基聚合物类似反应,用0.1的比例至25重量单体混合物的%,b)通过一个 通过加入(异氰酸根合)丙烯酸酯和/或(异氰酸根合)甲基丙烯酸酯的进一步反应,双键沿聚合物链中引入,和c)中的官能团和异氰酸酯基团之间的反应之后进行的聚合物的地方交联通过照射高能辐射。
