ABSTRACT:
A process for producing a lactone polymer which comprises reacting an ester compound synthesized from an alcohol and an acid or acid anhydride thereof with a lactone and a ring-opening polymerization initiator without being accompanied by condensation. The thus produced lactone polymer is effective for preventing shrinkage of thermosetting resins, particularly unsaturated polyester resins.
