    • PURPOSE:To obtain the title resin which can give a molding excellent in recovery from compressive deformation, flexibility, antistatic properties, staining resistance, etc., comprising a copolymer composed of hard segments comprising specified segments and two specified kinds of soft segments as an effective component. CONSTITUTION:A silicone-modified polyester resin is obtained by using a copolymer composed of hard segments comprising crystalline segments mainly consisting of polyester units and both of at least one member selected from the following group (A) and at least one member selected from the following group (B) as an effective component: group (A) consists of a polyalkylene ether glycol and an aliphatic polyester and a group (B) consists of an organosilane containing a group reactive with the above hard segment or with the compound of group (A) and an organopolysiloxane containing this reactive group. The above resin is thermoplastic and can be easily fabricated by injection molding or extrusion molding, and the obtained molding has good elongation set and impact resilience and excellent recovery from compression, staining resistance and antistatic properties.
