Abstract
Abstract A process for producing a thermoplastic resin composite comprising melt-kneading a crystalline resin forming a continuous phase and a non-crystalline resin forming a disperse phase is disclosed. In the process, the melt-kneading is carried out under a condition that a ratio of viscosity of the non-crystalline resin to .that of the crystalline resin is up to 2 to thereby form a disperse phase at least a part of which has a continuous structure. The resulting composite takes advantage of both the resins and exhibits excellent modulus of elasticity in high temperature and resistance to chemicals.
