| abstract |
The invention relates to novel polyionic polymersnin which the cationic part, consisting of unitsnrecurrent biaryliodonium, arylsulfonium, arylacylsulfonium,ndiazonium or organometallic, is associated with anionsnsulfonylimides or sulfonylmethylides.n n n These polymers are useful as photoinitiators for thencationic polymerization or crosslinking or for thenmodification of the solubility parameters of polymers usednespecially as photoresists. |
