Abstract
Process for the polymerization of ethylenically unsaturated compounds under the action of light in the presence of an azo compound, characterized in that starting from azo compounds of the general formula ** (see formula) ** Where n = 1 or 2 and with N = 2 ** (see formula) ** R'= alkyl groups with 1 to 8 c atoms, these two groups also being able to form a ring. X = oh, ocor'', -nh2, nh-co.r'', en lo que R "can be alkyl, cycloalkyl, aryl or aralkyl and in the case of n = 1, R = arilo R'= alkyl groups having 1 to 8 c atoms, these two groups also being able to form a ring, meaning ** (see formula) ** The intensity of the irradiated light is dimensioned in such a way that no thermal decomposition of the initiator used is produced.
