Vinyl ester adhesive compositions

A curable adhesive composition for anchoring materials in or to concrete or masonry, comprising: a. polymerizable vinyl ester corresponding to formula (II), wherein Ar is substituted or unsubstituted aromatic radical with a valence of at least two, R is independently a substituted or unsubstituted divalent radical derived from alkyl, oxyalkyl, arylalkyl, or oxyalkylaryl, R2 is independently H, substituted or unsubstituted vinyl carboxy radical, substituted or unsubstituted epoxy radical, or R, provided that the ratio of n to the number of vinyl carboxy R2 groups is, on average for the composition, from about 0.4 to about 2.0, for each Rx, x is independently 0 or 1, for each Oy, y is independently 0 or 1, for each (O-R2)z, z is independently 0 to 4, provided that at least one y must not be zero if z is zero, and n is from 1 to 5; b. an ethyleneically unsaturated monomer reactive with said polymerizable vinyl ester; c. curing catalyst; and d. activator, is disclosed.
