Abstract

DC60 (18/02/41) Compounds of formulas I, II, III, and IV (chemical formula) (I) (chemical formula) (II) (chemical formula) (III) (chemical formula) (IV) where Ar, for example, is a phenyl, biphenyl, or benzoylphenyl group that is not substituted or is substituted for Ar1, for example, is synonymous with Ar, Ar2 is a phenyl among others, x is a direct bond, Y is hydrogen, etc. R1 and R2, for example, are C1-C8, R3 among others is hydrogen or C1-C12 alkyls, R4 among others is C1-C12 alkyls or R3 and R4 combined are C3-C7 alkyls, R5, for example, is C1-C6 alkyls, and Z is a divalent radical. Given that at least One of the radicals Ar, Ar1, Ar2, Ar3, R1, R2, R3, R4, R5, or Y is replaced by 1 to 5 SH groups, or given that Y contains at least one -SS- group, as the light-dependent initiator for the polymerization of ethylenenichalytic unsaturated compounds. Compounds of formulas I, II, III, and IV (chemical formulas) where Ar, for example, is a phenyl, biphenyl, or benzoylphenyl group, which is either unsubstituted or substituted. Ar, for example, is synonymous with Ar, Are, which are phenyls among others. x is a direct bond, Y is hydrogen, etc. R1 and Re, for example, are C-C, R among others is hydrogen or C1-C12 alkyls, R4 among others is C1-C12 alkyls, or R3 and R4 combined are C3-C7 alkyls, R5, for example, is C1-C6 alkyls, and Z is a divalent radical. It is defined that at least one radical Ar, Ar1, Are, Ar3, R1, R2, R3, R4, R5, or Y is substituted by 1 to 5 groups of SH, or it is defined that Y has at least one -SS- group as the light-dependent initiator. For the polymerization of ethylenenichaline unsaturated compounds.
