An allyl vinyl ester resin comprises at least two species of terminally unsaturated residue derived respectively from (a) a compound having at least one terminal unsaturated group providing vinyl unsaturation and a carboxylic acid group or a reactive derivative thereof and (b) a compound having at least one terminal unsaturated group providing allyl unsaturation and a carboxylic acid group or a reactive derivative thereof. Each species derived from compounds (a) and (b) is present, independently, in at least one unsaturated ester compound comprising additionally (c) at least one residue derived from an epoxy compound having at least two epoxy groups and capable of reaction with a carboxylic acid or reactive derivative thereof, and (d) at least one half ester group pendant from an unsaturated ester chain of the unsaturated ester compound. |
