PURPOSE:To obtain electrical properties of high performance to satisfy heat resistance and flexible properties by preparing a thermoplastic resin constituted of a mixture composed of at least two kinds of ethylene group copolymers of specific composition and specifying the copolymerizing ratio of ethylene in said copolymers and mixing ratio of two kinds of copolymers. CONSTITUTION:Thermoplastic resin is a mixture of at least two kinds of ethyl ene group copolymers, and the mixture is formed with a copolyemr (I) and a copolymer (II). The copolymer (I) is formed at least with a unit oriented from ethylene and a unit at oriented at least one kind of monomer selected out of a group constituted of alpha,beta-unsaturated monocarboxylic acid, alpha,beta-unsaturat ed dicarboxylic acid, its dehydride and half ester. The copolymer (II) is formed with at least a unit oriented in ethylene and a unit oriented in an ethylene unsaturated monomer containing hydroxyl or glycidyl. The copolymerization ratio of ethylene in said copolymers is 30-99.5wt.% respectively, and the mixing ratio of the copolymer (I) in the total quantity of the copolymer (I) and the copolyemr (II) is 10-90wt.%. |
