POLYESTER-FURFURYL ALCOHOL COPOLYMERS CONTAINING METAL ATOMS

摘要

There are disclosed furfuryl alcohol copolymers of a polyester prepolymer of maleic acid or anhydride and a polyhydric alcohol which incorporate tungsten and/or molybdenum metal atoms. The metal atoms are incorporated into the copolymers by reacting the polyester prepolymer with a reaction product of tungsten or molybdenum and pyrrolidine.
