Abstract
A thermosettable composition comprising (1) an unsaturated polyester, (2) a block copolymer of a lactone, a conjugated diene and, optionally, a monovinylarene, and (3) a vinyl monomer is provided which shows improved compatibility and stability over a composition in which the block copolymer does not contain a polylactone block.
