    • An object of the present invention is to provide a rubber-steel hybrid cord which makes it possible to sufficiently reduce the proportion of an adhesion promoter or sulfur while maintaining good adhesiveness, and to provide a pneumatic radial tire using the same as a reinforcement layer.To achieve this object, a rubber-steel hybrid cord of the present invention is characteristically formed by twisting a plurality of sheath filaments or sheath strands around a core in which a periphery of and space surrounded by one or a plurality of core filaments or a core strand are coated or filled with a filler rubber (A) containing an adhesion promoter, thereby forming a multilayer-twist steel cord or a multi-twist steel cord, and coating an outer surface of the multilayer-twist steel cord or the multi-twist steel cord with a coating rubber (C). Further, an amount of an adhesion promoter contained in the coating rubber (C) is equal to or more than an amount of the adhesion promoter contained in the filler rubber (A).
    • 本发明的目的是提供一种橡胶 - 钢混合帘线,其可以在保持良好的粘合性的同时充分降低粘合促进剂或硫的比例,并且提供使用其作为增强层的充气子午线轮胎。 为了实现这个目的,本发明的橡胶 - 钢混合帘线特征在于通过将多个鞘细丝或鞘股线缠绕在其周围并由一个或多个芯丝或芯部围绕的空间 将线材涂布或填充有含有粘合促进剂的填充橡胶(A),从而形成多股扭曲钢丝帘线或多捻钢丝帘线,并且涂覆多层捻线钢丝绳的外表面或多捻 钢丝绳带涂层橡胶(C)。 此外,涂布橡胶(C)中所含的粘合促进剂的量等于或大于填充橡胶(A)中所含的粘合促进剂的量。

    • A polyether polyol produced by using an N-aminoethylpiperazine-ethylene oxide aduct as an initiator and addition-polymerizing an alkylene oxide thereto and having a molecular weight of about 2000 to 7000; a process for producing a flexible urethane foam starting with the above polyether polyol; a process suited for the production of a hot-cure urethane foam which comprises using the above polyether polyol with a hydroxyl value of 40 to 80 mg KOH/g and, as a blowing agent, 4.6 to 6.0 weight parts of water based on 100 weight parts of the polyol; and a process suited for the production of a cold-cure urethane foam which comprises using the above polyether polyol with a hydroxyl value of 23 to 50 mg KOH/g and, as a blowing agent, 2.5 to 5.0 weight parts of water on the same basis.The use of the polyether polyol enables the production of a low-density, low-hardness flexible urethane foam using a small amount of water, without requiring any environment-unfriendly chlorofluorocarbon and without being accompanied by deterioration of humid age compression set and other characteristics.
