Abstract
Abstract Polyfunctional cationically polymerizable styryloxy compound of the formula ##STR1## where R 1 and R 2 are H, or one of R 1 and R 2 are H and the other is methyl; R 3 and R 4 are H, lower alkyl, or alkoxy if R 2 is not methyl; R 5 is a divalent hydrocarbon radical; G is any multivalent organic or inorganic radical free of amino, aliphatic hydroxyl, aliphatic thiol or other groups which interfere with cationic polymerization; and n is an integer of two or more.
