Abstract
The invention relates to novel N-substituted imides and polymerizable compositions comprising these N-substituted imides. The invention further relates to the use of N-substituted imides as polymerization initiators. The imides are compounds of the formula (I) and (II) wherein n is 1 or 2; m is 1 or 2; Rand Rare each, independently of one another, hydrogen, C-Calkyl, C-C-alkenyl C-Caryl, aralkyl, C-Ccycloalkyl, each of which may be substituted by halogen, C-C-alkyl, hydroxy, C-Calkoxy, carbonyl, C-Calkoxycarbonyl; or Rand Rtogether with the adjacent —CO—N—CO— group may form a monocyclic, bicyclic or polycyclic ring, said ring having up to 50 non hydrogen atoms and wherein said ring may contain the structural element (formula III) more than once; Rif n is 1, is C-Calkyl, C-Caryl, aralkyl, C-Ccycloalkyl, ORor SR, NRR; wherein Rif n is 2, is C-Calkylene, C-Carylene, xylylene Rand R, correspond to Rand R; Rif n is 1, is hydrogen, C-Calkyl, C-Caryl, aralkyl, C-Ccycloalkyl, NRR; wherein Rif n is 2, is C-Calkylene, C-Carylene, xylylene; Ris hydrogen, C-Calkyl, C-Caryl, aralkyl, C-Ccycloalkyl, each of which may be substituted by halogen, C-C-alkyl, hydroxy, C-Calkoxy, carbonyl, C-Calkoxy-carbonyl; or Rand Ror Rand Rform together with the N-atom attached to Ra 5-6 membered ring, optionally interrupted by —NH—, —N(C-Calkyl)-, —O— and/or S-atoms.
