ABSTRACT:
A composition is described which thermosets when admixed with a free radical generating catalyst which composition comprises (A) an unsaturated polyester resin or vinyl ester resin, (B) a reactive monomer prepared by reacting (1) an aromatic material containing, per molecule, one polymerizable ethylenically unsaturated group and one group containing an ether linked epoxide group; and (2) a material containing at least one oxyalkylene group and is terminated in a group having at least one hydrogen atom which is reactive with an ether linked epoxide group, and (C) a polymerizable ethylenically unsaturated non-resinous monomer different from Component (B).
