    摘要： An ethylene-.alpha.-olefin-non-conjugated diene copolymer rubber composition comprising a low molecular weight component copolymer composed of an ethylene-.alpha.-olefin-non-conjugated diene copolymer having a Mooney viscosity (ML.sub.1+4, 100.degree. C.) of 10 to 150, an .alpha.-olefin content of 30 to 60% by weight and an iodine value of 37 to 65, and a high molecular weight component copolymer composed of an ethylene-.alpha.-olefin-non-conjugated diene copolymer having a Mooney viscosity (ML.sub.1+4, 100.degree. C.) of 100 to 500, an .alpha.-olefin content of 15 to 50% by weight and an iodine value of 3 to 15, the ratio of the iodine value of the low molecular weight component copolymer to the iodine value of the high molecular weight component copolymer being at least 4/1. The above composition can inhibit a gel from being produced during processing and achieve a high degree of cross-linking and is excellent in compression set, shape-retention and sponge surface skin.

    摘要： A chemical mechanical polishing pad of the present invention has the following two groups of grooves on the polishing surface: (i) a group of first grooves intersect a single virtual straight line extending from the center toward the periphery of the polishing surface and have a land ratio represented by the following equation of 6 to 30: Land ratio=(P−W)÷W (where P is the distance between adjacent intersections between the virtual straight line and the first grooves, and W is the width of the first grooves); and (ii) a group of second grooves extend from the center portion toward the peripheral portion of the polishing surface and consist of second grooves which are in contact with one another in the area of the center portion and second grooves which are not in contact with any other second grooves in the areas of the center portion. The chemical mechanical polishing pad of the present invention has a high polishing rate and excellent in-plane uniformity in the amount of polishing of the surface to be polished even when the amount of an aqueous dispersion for chemical mechanical polishing is made small.
