<P>PROBLEM TO BE SOLVED: To provide a material capable of being easily and homogeneously dispersed in a resin material in melting and kneading, maintaining the dispersion diameter small, improving mechanical properties of various resin materials and reducing the addition amount to develop the same physical properties, by using a powder resin. <P>SOLUTION: The powder resin (A) is a powder resin composition which comprises a thermoplastic resin (a-1), and an olefinic resin (a-2) and/or a fatty acid (a-3), and may further comprise an anionic and/or nonionic surfactant (a-4), and which has an average primary particle diameter of 50 nm to 50 μm. A polymer alloy comprises the resin (A) and a resin (B). A powder resin composition can be used as a dispersed phase when the polymer alloy is manufactured, and has higher actions and effects than heretofore, including being capable of being easily and homogeneously dispersed in a resin material in melting and kneading, maintaining the dispersion diameter small, improving mechanical properties of various resin materials and reducing the addition amount to develop the same physical properties. <P>COPYRIGHT: (C)2012,JPO&INPIT |
