摘要
The present disclosure is directed to a UV-curable non-isocyanate polyuria polymer and a UV-curable coating composition containing the same. The UV-curable non-isocyanate polyurea polymer has one or more ethylenically unsaturated functional groups and the ethylenically unsaturated functional groups are attached to nitrogen atoms present in a backbone urea segment via -C(=O)- linkage. The non-isocyanate polyurea polymer is prepared by: (i) providing an ethylenically unsaturated compound having one or more carboxylic acid functional groups; and (ii) reacting said ethylenically unsaturated compound having one or more carboxylic acid functional groups with a multi-carbodiimide polymer to form the non-isocyanate polyurea polymer.
