Resin composite, film, methods of producing the resin composite and the film, molded product, and article

A method of producing a resin composite, the method comprising:

• melt-compounding a resin composite that contains 65 to 99 parts by mass of a methacrylic resin (A) and 1 to 35 parts by mass of a triblock copolymer (B)
• at a shear rate of 10/sec to 1000/sec and at a temperature of from 180° C. to 300° C.,
• wherein
• the methacrylic resin (A) contains no less than 80% by mass of a structural unit derived from methyl methacrylate and has a melt viscosity η(A) of 1500 to 3500 Pa·s at 220° C. and a shear rate of 122/sec;
• the triblock copolymer (B) contains a methacrylic acid ester polymer block (b2) coupled to each of two ends of an acrylic acid ester polymer block (b1), where a content of the acrylic acid ester polymer block (b1) is 30% to 60% by mass and a content of the methacrylic acid ester polymer block (b2) is 40% to 70% by mass;
• the triblock copolymer (B) has a melt viscosity η(B) of 75 to 1500 Pa·s at 220° C. and a shear rate of 122/sec;
• and
• a ratio η(A)/η(B) of the melt viscosity η(A) to the melt viscosity η(B) is from 1 to 20.
