PROBLEM TO BE SOLVED: To provide a polymer having a main chain of a weather-resistant vinyl polymer and a polymerizable functional group at a terminal, and the polymer and a photopolymerization initiator. It is an object of the present invention to provide a light and electron beam curable composition containing as a main component. SOLUTION: The present invention relates to a vinyl polymer having a (meth) acryloyl-based functional group at a terminal, and this polymer is used for conversion of a terminal functional group of a polymer produced by living radical polymerization or the like. Further, a photo- and electron-beam curable composition is obtained by adding a photopolymerization initiator such as a photoradical initiator to the polymer. |
