Aromatic vinyl ether compounds represented by Formula (1) or by Formula (2)
wherein each R and R′ is a hydrogen atom or a group represented by Formula (3)
and wherein the remaining variables are as defined in the specification, provided that at least one pR in Formula (1) and at least one uR in Formula (2) is a Formula (3) group. These aromatic vinyl ether compounds are useful as, e.g., curing agents for cationic polymerization.
