The present invention relates to dephenolic compounds, an example of which is shown below, which are functionalized, and polymers formed from the same.
Polymers formed from the functionalized diphenolics are expected to have controllable degradation profiles, enabling them to release an active component over a desired time range. The polymers are also expected to be useful in a variety of medical applications.

To provide a polyester resin composition whereby formation of a cyclic trimer, etc. during melt molding is suppressed, and little soiling or the like is observed during the molding, and a method for its production. A method for producing a polyester resin composition (C), which comprises melt-kneading a polyester resin (A) which satisfies the following formulae (1), (2) and (3) and a polyester resin (B) which satisfies the following formula (4). The polyester resin composition (C) obtained by the method, and a molded product such as a film made from such a composition.
