Abstract
Abstract This invention relates to epoxy vinyl ethers having the formula: ##STR1## where R is a polyvalent linear, branched or cyclic hydrocarbon radical having from 2 to 20 carbon atoms, optionally substituted with alkyleneoxy; A is branched or linear C 1 to C 4 alkylene; B is halogen or lower alkyl; m has a value of from 0 to 4; n has a value of from 0 to 20; p has a value of from 1 to 5; and T is ##STR2## when p is one, and is ##STR3## or a mixture of ##STR4## and ##STR5## when p is greater than one.
