Abstract

Organic polymer compounds having semi-telechelic olefinic unsaturation, which correspond to the general formula: ##STR1## in which V is the radical of an organic compound containing at least one polymerizable ##STR2## group and another group capable of reacting with the functional groups of organic compounds having radicals represented by W and Y; W is the radical of a chain transfer agent RSH, R being an organic radical having at least one hydroxyl or carboxyl group; X is the radical of an organic compound containing a polymerizable ##STR3## group; Y is the radical of an organic compound containing a polymerizable ##STR4## group and at least one other reactive group selected from hydroxyl, carboxyl, acid anhydride and epoxy groups; y is 0 or a whole number of from 1 to 10; x is the number of moles of X necessary to enable the chain --(X).sub.x --(Y).sub.y -- to have a molecular weight from 1000 to 10,000 and H is the hydrogen atom detached from the chain transfer agent RSH, the radical RS of which is represented by W in the above general formula; the radicals X and the radicals Y being distributed statistically along the polymer chain --(X).sub.x --(Y).sub.y -- in accordance with …
