Patent ID: 7960473

Claim:
A thermoplastic resin composition comprising a thermoplastic resin (A) which is at least one selected from polyamide resins, polyester resins, polyphenylene sulfide resins, polyphenylene oxide resins and polycarbonate resins and a reactive functional group-containing resin (B) having a molecular chain, wherein reactive functional groups of the reactive functional group-containing resin (B) are at least one selected from amino groups, carboxyl groups, carboxyl metal salt, epoxy groups, acid anhydride groups and oxazoline groups, and the resin (B) has the reactive functional groups in the molecular chain, wherein the morphology of said resin composition observed by transmission electron microscopy tomography is such that either the resin (A) or the resin (B) forms a continuous phase, while the other resin forms a dispersed phase, that three-dimensionally connective structures (Cs) containing said continuous phase component are formed in the respective dispersed phase particles of said dispersed phase, and the area of said connective structures (CS) occupying a section of each dispersed phase particle Dp with an average particle size of 1,000 nm or less of said dispersed phase is 10% or more.
