ResumoAbstract Telomers were prepared from acrylic or methacrylic acid and CCl 3 Br, C 12 H 25 SH, C 18 H 37 SH or C 8 F 17 C 2 H 4 SH by initiation with 2,2'‐azoisobutyronitrile. The transfer constant of CCl 3 Br and the thiols, which are about 0,03 and 0,5, respectively, were determined. These telomers were used as supports of photopolymerizable functions, which were introduced by grafting of 2,3‐epoxypropyl methacrylate, catalysed with dodecyldimethylamine. The reactions were followed by 1 H NMR, elemental analyses, tonometrie, and especially by GPC and titration of the acid functions. The grafting telomers, holding many acrylic functions which react upon UV and electron irradiation, give photoreticulated varnish coatings with very interesting properties.
