摘要： A polybutadiene rubber composition comprising (A) a polybutadiene rubber obtained by solution polymerization and having a Mooney viscosity (ML.sub.1+4.sup.100.degree. C.) of 60-110 and a 1,4-configuration content of not less than 60%, preferably not less than 70%, and (B) a polybutadiene polymer obtained by solution polymerization and having a viscosity-average molecular weight of 20,000-140,000, preferably 40,000-100,000, and a 1,4-configuration content of not less than 60%, preferably not less than 70%, in which composition the weight ratio of (A)/(B) is 100/5-100/150, preferably 100/35-100/100, and the Mooney viscosity (ML.sub.1+4.sup.100.degree. C.) of which composition is 20-70. This composition is high in tackiness in the unvulcanized state and also excellent in the physical properties of vulcanizate.

摘要： A method and apparatus adapted to bunch together a predetermined number of inverted PTPs and uninverted PTPs into a bundle, and then transfer each PTP bundle to a bucket conveyor which moves intermittently in parallel with a conveying passage. A multitude of PTPs, a portion of which are inverted with respect to the conveying direction and the rest of which are not inverted, are conveyed along a first conveying passage while maintaining the blistered surfaces of the inverted and uninverted PTPs in parallel with each other. A selected portion of the PTPs being conveyed in the first conveying passage is pinched and separated from the same passage. The separated PTPs are bunched together while the spacing between the separated PTPs is narrowed in the conveying direction. The bunched PTPs are transferred onto a second conveying passage across the first conveying passage. The bunched PTPs are loaded into a bucket provided on a bucket conveyor which intermittently travels along the second conveying passage.
摘要翻译：一种适于将预定数量的反向PTP和未反相PTP聚束到束中的方法和装置，然后将每个PTP束传送到与输送通道平行移动的斗式输送机。多个PTP，其一部分相对于输送方向反转，其余部分不反转，沿着第一输送通道输送，同时保持反相和未反转的PTP的起泡表面彼此平行。在第一输送通道中输送的PTP的选定部分被夹紧并与同一通道分离。分离的PTP聚集在一起，而分离的PTP之间的间隔在输送方向上变窄。聚束的PTP被转移到穿过第一输送通道的第二输送通道上。聚束的PTP被装载到设置在沿着第二输送通道间歇地行进的斗式输送机上的桶中。

摘要： A process for producing cis-4,5-dihydro-4,5-dihydroxyphthalic acid which comprises producing cis-4,5-dihydro-4,5-dihydroxyphthalic acid and/or a salt thereof from phthalic acid and/or a salt thereof using a microorganism whose activity to decompose cis-4,5-dihydro-4,5-dihydroxyphthalic acid and/or a salt thereof has disappeared or diminished, acidifying the product system unless it is acidic, and then extracting therefrom cis-4,5-dihydro-4,5-dihydroxyphthalic acid with such an organic solvent that it is miscible with water in any proportion and the mixture of the organic solvent with water can be separated into two layers upon adding a salt thereto, in the presence of a salt, or with an alcohol having 4 carbon atoms. The process enables one to produce cis-4,5-dihydro-4,5-dihydroxyphthalic acid from phthalic acid and/or its salt in a high yield.
