  • Process for the photopolymerization of ethylenically unsaturated compounds
    Patent number: 4001017
    Abstract: In photopolymerization, the polymerization process is activated or initiated by radiation, for example in the region of ultraviolet or visible waves. According to the present invention ethylenically unsaturated compounds can now be polymerized advantageously with the aid of a new catalyst system which consists of a diazine compound, preferably a quinoxaline and an electron donor, which together act as a photoredox pair.
