The invention relates to urethane(meth)acrylates and to a process for their production which comprises transesterification of hydroxyalkyl carbamates with an (meth)acrylate of formula [CH2=CR29-CO-O-]t-R30 wherein R29 is hydrogen or methyl, and R30 represents an alkyl, optionally substituted by hydroxy, which may contain from 1 to 10 ether bridges group, from 1 to 10 -CO- bridges and/or from 1 to 5 -O-CO- bridges, and at least one carbonate of formula (IX) and/or a diester of formula (X) wherein each R31, each R32, each R33, each R34 is, independently, chosen from the group of alkyl and aryl, and R35 is alkylene, alkenylene or arylene.
该发明涉及氨基甲酸酯(甲基)丙烯酸酯以及它们的生产方法,该方法包括将羟基烷基氨基甲酸酯与具有以下结构的(甲基)丙烯酸酯进行酯交换反应:[CH2=CR29-CO-O-]t-R30,其中R29为氢或甲基,R30代表一种烷基,该烷基可以选择性地被羟基取代,可能含有1到10个醚桥基团,1到10个-CO-桥基和/或1到5个-O-CO-桥基,并且至少含有一个具有以下结构的碳酸酯(IX)和/或一个具有以下结构的二酯(X),其中每个R31、每个R32、每个R33、每个R34独立地选择自烷基和芳基群,而R35为烷基、烯基或芳基。
