Abstract
Radiation- or thermally-initiated cationically-curable styrene oxides of the structure ##STR1## are suitable for use in cationically curable adhesive and coating compositions.
Claims4
A cationically-curable adhesive or coating composition comprising
- (a) a radiation- or thermally-initiated cationically-curable compound having the structure ##STR10## in which R.sup.1 to R.sup.4 independently represent hydrogen, or aliphatic, alicyclic or aromatic groups, which may contain heteroatoms, characterized in that they do not hinder the cationic polymerization of the epoxy functionality either through steric interaction or through the action of a Lewis base;
- y is an integer 1-6, w is an integer 0-5, provided that y+w.ltoreq.6;
- and
- (b) a cationic photo- or thermal-initiator;
- and
- (c) one or more alcohols or polyols.
