1. A polymer comprising (A) from 10 to 97 weight percent of the reaction product mixture of a polycaprolactone polyol and maleic anhydride and (B) from 3 to 90 weight percent of an ethylenically unsaturated monomer polymerized with (A);

  • wherein said reaction product mixture (A) is the adduct of a polycaprolactone polyol having at least two hydroxyl groups in the molecule, a hydroxyl number of from 4 to 600 and an average molecular weight of from 290 to 25,000 with from 0.1 to 1 anhydride equivalent per hydroxyl equivalent in said polyol initially charged.
