    • The present invention relates to a process for preparing low-viscosity, allophanate-containing and NCO-free polyurethane prepolymers curable by actinic radiation, and to the products obtainable by this process. The prepolymers have residual monomer contents of less than 0.5% by weight and an NCO content of less than 1% by weight, and are prepared by a process in which A) diisocyanates, B) hydroxy-functional compounds containing groups which react with ethylenically unsaturated compounds on exposure to actinic radiation, and C) polyester, polyether or polycarbonate polyols having a functionality of at least 1.9 and a number-average molecular weight (Mn) of at least 1000 g/mol, D) optionally in the presence of a catalyst, are reacted to form NCO-group-containing prepolymers having radiation-curing groups, which are subsequently reacted E) optionally after addition of monofunctional isocyanates in the presence F) of an allophanatization catalyst to give allophanate-containing prepolymers, the ratio of NCO groups of the compounds from A) to the OH groups of the compounds from B) and C) being 1.45:1.0 to 1.1:1.0 and the ratio of the OH groups from B) to the OH groups from C) being 8.0:1 to 1.5:1.
    • 本发明涉及一种制备可通过光化辐射固化的低粘度，含有脲基甲酸酯和不含NCO的聚氨酯预聚物和通过该方法获得的产品的方法。 预聚物的残留单体含量小于0.5重量％，NCO含量小于1重量％，并且通过以下方法制备：A）二异氰酸酯，B）含有与烯属不饱和基团反应的基团的羟基官能化合物 化合物暴露于光化辐射，以及C）官能度为至少1.9，数均分子量（Mn）至少为1000g / mol的聚酯，聚醚或聚碳酸酯多元醇，D）任选地在催化剂存在下 反应形成具有放射线固化基团的含有NCO基团的预聚物，其随后反应E）任选地在加入单官能异氰酸酯的情况下，在脲基化催化剂存在下，得到含脲基甲酸酯的预聚物，NCO基团 的来自A）的化合物与来自B）和C）的化合物的OH基团的摩尔比为C：1.45:1.0至1.1:1.0，并且B）中的OH基与C）中的OH基团的比例为8.0:1至1.5 ：1。
