Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 118 words
A radiation- or thermally-initiated cationically-curable compound having the structure: ##STR6## in which Q represents aliphatic, alicyclic or aromatic groups, which may contain oxygen, nitrogen, sulfur or silicon, 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; and R 1 , R 2 , R 4 , R 5 , R 7 and R 8 independently represent hydrogen, 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; and w and z are independently integers of 1-5.
Claim 2
Dependent Claim 118 words
A radiation- or thermally-initiated cationically-curable compound having the structure: ##STR6## in which Q represents aliphatic, alicyclic or aromatic groups, which may contain oxygen, nitrogen, sulfur or silicon, 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; and R 1 , R 2 , R 4 , R 5 , R 7 and R 8 independently represent hydrogen, 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; and w and z are independently integers of 1-5.
Claim 3
Dependent Claim 18 words
An adhesive composition comprising the radiation- or thermally-initiated cationically-curable compound of claim 1 and a photo- or thermal-initiator.
Claim 4
Dependent Claim 18 words
A coating composition comprising the radiation- or thermally-initiated cationically-curable compound of claim 1 and a photo- or thermal-initiator.
