Abstract
Telomers and cotelomers with at least one sequence which can be cross-linked by light, and a method of preparing them. They are of the general formula ##STR1## wherein the taxogen links --(X.sub.i)-- belong to the group made up of 2-hydroxy ethyl acrylate and methacrylate, acrylic or methacrylic acid, vinyl alcohol and allyl alcohol; the ##STR2## links emanate from the same taxogen X.sub.i, esterified by means of a group with at least one photo-crosslinkable double bond in its molecule; and where 1<x+y.ltoreq.1000, Z being chosen from the group --H, --Cl, --Br; and where R may be a simple or macromolecular radical, in the latter case leading to the formation of dual sequence cotelomers. The manufacturing process comprises telomerisation by redox or radical catalysis, followed by grafting on the photo-cross-linkable group, the first phase of telomerisation being duplicated in the case of a cotelomer. The main application for the products is in coating metals.
