Abstract
A thermoplastic resin composition production method wherein melt-kneading is performed in a stretched flow when producing a thermoplastic resin composition as specified in the paragraph (I) or (II) below: (I) a thermoplastic resin composition comprising a Thermoplastic resin (A) and a Resin (B) with a reactive functional group; (II) a thermoplastic resin composition comprising a Thermoplastic resin (A), a Thermoplastic resin (C) that is different from the Thermoplastic resin (A), and a Compound (D) with a reactive functional group.
Claims11
A thermoplastic resin composition production method wherein melt-kneading is carried out in an extruder in which the flow effect pressure drop across the zone for performing melt-kneading in a stretched flow (stretched flow zone) is 100 to 1,000 kg/cm2 when producing a thermoplastic resin composition as specified in paragraph (I) or (II) below:
- (I) a thermoplastic resin composition comprising a Thermoplastic resin (A) and a Rubber-like polymer (B) with a reactive functional group
- (II) a thermoplastic resin composition comprising a Thermoplastic resin (A), a Thermoplastic resin (C) that is different from the Thermoplastic resin (A), and a Compound (D) with a reactive functional group.
