Abstract: A process for producing a lactone polymer comprises reacting an ester compound synthesized from an alcohol and an acid or acid anhydride with a lactone and a ring-opening polymerization initiator. When the ester compound is a polyester the thus produced lactone polymer is effective for preventing shrinkage of thermosetting resins, particularly unsaturated polyester resins.

Abstract: A modified porous membrane can be prepared by dissolving an aromatic polymer having a thioether group in an organic solvent, forming a membrane of the aromatic polymer from the resultant solution by phase conversion and oxidizing the formed membrane. This modified porous membrane can effectively be utilized in a filtration method wherein ultrafiltration, reverse osmosis, fine filtration, gas separation, vapor permeation or pervaporation is conducted.
