(57) [Summary] [Structure] A thermoplastic resin A1 which does not adhere to each other in a laminate comprising at least three thermoplastic resin layers. An intermediate layer sandwiched between a first layer and a second layer made of thermoplastic resin B1 and thermoplastic resin B1, respectively, has thermoplastic resin A2 and thermoplastic resin B having adhesiveness with thermoplastic resin A1. 1 and a thermoplastic resin B2 having an adhesive property as a main component, the thermoplastic resin composition forming a sea / island structure, and the thermoplastic resin A2 near the interface with the first layer in the intermediate layer. Is a sea phase, the thermoplastic resin B2 forms an island phase, and the thermoplastic resin B2 forms a sea phase and the thermoplastic resin A2 forms an island phase near the interface with the second layer in the intermediate layer. And a thermoplastic resin laminate. [Effect] It is possible to continuously manufacture a laminate in which two layers made of thermoplastic resins that are not adhered to each other are firmly adhered to each other by simultaneous coextrusion molding. |
