Patent ID: 11739187

Abstract:
Provided are a resin composition, a production method thereof, and a molded product and a multilayer structure each including such a resin composition. The resin composition enables: even in the case in which a film formation temperature is high, excessive elevation of torque to be inhibited with occurrence of neck-in during film formation being prevented; a molded product superior in appearance characteristics to be formed continuously for a long time period, with defects such as fish eyes and streaks being prevented; and further a thermoformable multilayer structure to be produced continuously for a long time period, the thermoformable multilayer structure being capable of providing a thermoformed product superior in appearance characteristics. A resin composition containing: an ethylene-vinyl alcohol copolymer (A) having an ethylene unit content of 20 to 60 mol %; and a boron compound (B), the boron compound (B) including a free boric acid (C), with a content of the boron compound (B) with respect to the ethylene-vinyl alcohol copolymer (A) being 100 ppm or more and 5,000 ppm or less in terms of orthoboric acid, and a proportion of the free boric acid (C) in the boron compound (B) being 0.1% by mass or more and 10% by mass or less in terms of orthoboric acid.
