Claims20
A resin composition which exhibits anisotropism when melted, comprising two components uniformly mixed with each other which following injection molding is capable of exhibiting a tensile strength and a flexural strength which exceeds that of each of the two components when separately injection molded, the first component being a resin which has no flexible skeleton and a rigid skeleton selected from the group consisting of polyester, polyesteramide, polyamide, polyazomethine, polyurethane, polysiloxane, and polyphosphazene, and mixtures of the foregoing, and exhibits anisotropism when melted, and the second component being a resin which has a rigid skeleton selected from the group consisting of polyester, polyesteramide, polyamide, polyazomethine, polyurethane, polysiloxane, and polyphosphazene, and mixtures of the foregoing, and a flexible skeleton selected from the group consisting of polyarylate, polyalkylene terephthalate, polycarbonate, polyethersulfone, polyacrylate, and mixtures of the foregoing.
