Abstract
The invention relates to acrylic telomers with grafts which can be cross linked by light, methods of synthesizing them and their applications. The telomers comprise a telogen of the mercaptan family, in particular dodecanethiol, and links of a taxogen of the acrylic family, some of which are grafted. The telomers are synthesized semi-continuously by radical initiation in the presence of initiators such as azobisisobutyronitrile, at a temperature below 75.degree. C., making it possible to obtain a number of links adapted to the desired applications. Grafting is carried out by means of glycidyl and aziridinyl groups.
