ABSTRACT:
Free radically curable monomer compositions, particularly anaerobic compositions, which include an accelerator compound of the formula: ##STR1## where n is an integer; G is an n valent radical providing compatibility of the accelerator with the curable monomer; X is 0, 0--0, S or NR"; R' is an aromatic group which may be substituted or unsubstituted; and, R" is H, alkyl or aryl.
The accelerator compounds are readily prepared by reacting an aromatic sulfonyl isocyanate with a compound having an isocyanate reactive hydrogen atom.
