Definitions
- the present invention relates to a method for producing a heat-resistant resin composition having excellent dispersibility of a maleimide-based copolymer.
- ABS resin is a thermoplastic resin whose main components are acrylonitrile, butadiene, and styrene. Taking advantage of its excellent mechanical strength, appearance, chemical resistance, moldability, etc., it makes use of its excellent mechanical strength, appearance, chemical resistance, moldability, etc. Widely used in. On the other hand, heat resistance may be insufficient in applications that require heat resistance, such as automobile interior materials.
- the techniques for improving heat resistance include the following, and maleimide-based copolymers, ⁇ -methylstyrene-based copolymers, and the like are used (Patent Documents 1 and 2). Further, in recent years, progress has been made in increasing the torque of the twin-screw extruder and deepening the groove of the screw, so that a high discharge amount has become possible.
- An object of the present invention is to provide a method for producing a heat-resistant resin composition having excellent dispersibility of a maleimide-based copolymer.
- a heat-resistant resin including a step of melt-kneading a maleimide-based copolymer (A) and at least one resin (B) selected from ABS resin, ASA resin, AES resin, and SAN resin with an extruder.
- the ratio of the melt viscosity of the maleimide-based copolymer (A) to the melt viscosity of the resin (B) at a shear rate of 120 / sec and the cylinder temperature of the kneaded portion of the extruder is , 1.0 or more and less than 3.4, a method for producing a heat-resistant resin composition.
- the method for producing the heat-resistant resin composition of the present invention is excellent in the dispersibility of the maleimide-based copolymer, the dispersibility in a resin such as ABS resin is also sufficient. Therefore, a molded product having a good dispersion state of the maleimide-based copolymer and no appearance defect can be obtained even under a high discharge rate condition using a screw having a deep groove which is slightly inferior in the dispersion ability.
- a maleimide-based copolymer (A) and at least one resin (B) selected from SAN resin, ABS resin, ASA resin, and AES resin are melt-kneaded by an extruder. It is a heat-resistant resin composition obtained by the above.
- the maleimide-based copolymer (A) is a copolymer having a maleimide-based monomer unit and a styrene-based monomer unit.
- an acrylonitrile-based monomer unit and an unsaturated dicarboxylic acid anhydride-based monomer unit can be further provided.
- the maleimide-based monomer unit includes, for example, N-alkylmaleimide such as N-methylmaleimide, N-butylmaleimide, and N-cyclohexylmaleimide, and N-phenylmaleimide, N-chlorphenylmaleimide, and N-methylphenylmaleimide. N-methoxyphenylmaleimide, N-tribromophenylmaleimide and the like. Among these, N-phenylmaleimide is preferable.
- the maleimide-based monomer unit may be used alone or in combination of two or more.
- a raw material made of a maleimide-based monomer can be used as for the maleimide-based monomer.
