Molding of ABS-based resin and its producing process

A molding of an ABS-based resin has rubber particles located at a depth of 0.5-1.5 mu m from a surface of the molding, and the particles morphologically comprise at least the following two types of particles: (1) A particles having an a/b ratio not greater than 1.5, wherein a and b represent a major...

Zusammenfassung:	A molding of an ABS-based resin has rubber particles located at a depth of 0.5-1.5 mu m from a surface of the molding, and the particles morphologically comprise at least the following two types of particles: (1) A particles having an a/b ratio not greater than 1.5, wherein a and b represent a major axis and a minor axis, respectively, and (2) B particles having an a/b ratio not smaller than 5, wherein a and b have the same meanings as defined above. When a section taken by a microtome in parallel with a surface of the molding is observed in an electron micrograph, and assuming that the total area of the rubber particles as observed in the electron micrograph is 100%, the total area of the A particles accounts for at least 10% and that of the B particles is in a range of 0.01-90%.
