    • Graft-copolymers for improving impact strength comprising a relatively large quantity of an elastomeric trunk polymer, such as acrylonitrile/styrene/butadiene resins and methyl methacrylate/styrene/butadiene resins, have some undesirable powder characteristics, for example, poor fluidity and an easily blocking property.However, by blending a graft-copolymer of this type with a graft-copolymer comprising a relatively small quantity of an elastomeric trunk polymer in slurry form or dry state, it is possible to obtain a graft-copolymer blend with improved powder characteristics without significantly lowering the effect of improving the impact strength of the former graft-copolymer.The graft-copolymer blend thus obtained, when blended with a hard resin such as polyvinyl chloride, provides a resin composition with high impact strength.
    • 用于改善冲击强度的接枝共聚物包括相对大量的弹性体树脂聚合物,例如丙烯腈/苯乙烯/丁二烯树脂和甲基丙烯酸甲酯/苯乙烯/丁二烯树脂,具有一些不期望的粉末特性,例如流动性差和容易堵塞 属性。 然而,通过将这种类型的接枝共聚物与包含相对少量的浆料形式或干燥状态的弹性体树脂聚合物的接枝共聚物共混,可以获得具有改进的粉末特性而不显着降低的接枝共聚物共混物 改善前接枝共聚物冲击强度的效果。 由此获得的接枝共聚物共混物当与诸如聚氯乙烯的硬树脂共混时,提供了具有高冲击强度的树脂组合物。

    • A contact probe having a plunger; a top contacting member which is provided at a tip end of the plunger and is brought into contact with an electrode of a semiconductor device; a bottom contacting member which is brought into contact with an electrode of a testing board; and an elastic member for urging the top contacting member and the bottom contacting member in opposite directions away from each other. The plunger is formed into a cylindrical shape and includes a through-hole which penetrates through the plunger in an axial direction thereof. The top contacting member includes a plurality of mountain-shaped sharp portions at a tip end thereof, and each of the sharp portions is asymmetrical with respect to a straight line that passes through a peak of the sharp portion and extends along an axial direction of the plunger, and is bent toward a center line of the plunger.
