    • The preparation of vinyl chloride-type polymers by suspension polymerization of vinyl chloride monomers in the presence of monomer-soluble polymerization initiators, wherein the monomer-soluble polymerization initiators utilized are a combination of (A) a compound which possesses neither a benzene ring nor an alkoxyl group, and has a half-life of 10 hours at 0.1 mol/l concentration in benzene solution at a temperature of 40.degree.-50.degree. C., and (B) 1-cyclohexyl-1-methylethylperoxy pivalate.This method yields vinyl chloride-type polymers the qualities of which such as an initial colorization and thermal stability are effectively improved, without being affected by the limitations accompanied by the insufficient cooling capacity of the polymerization vessel in general. The preparative method further enables one to effectively avoid scale deposition in the polymerization vessel.
    • 在单体可溶性聚合引发剂存在下,通过氯乙烯单体的悬浮聚合制备氯乙烯类聚合物,其中所用的单体可溶性聚合引发剂是(A)不具有苯环的化合物和 烷氧基,在40〜-50℃的温度下,在苯溶液中以0.1mol / l的浓度具有10小时的半衰期,(B)1-环己基-1-甲基过氧基新戊酸酯。 这种方法产生氯乙烯型聚合物,其质量如初始着色和热稳定性有效地得到改善,而不受通常聚合容器冷却能力不足的限制的影响。 制备方法还能够有效地避免聚合容器中的结垢沉积。

    • A conveyor chain constructed so as to prevent a leakage of lubricant oil to the outside. The conveyor chain comprises a plurality of bearing elements operable to revolve in a raceway between an outer circumferential surface of a bush and an inner circumferential surface of a roller. A pair of right and left thrust bearing annular members are press-fitted onto the outer circumferential surface of the bush and are positioned between the inner side surface of an inner link plate and the outwardly-facing end surfaces of the bearing elements. Annular sealing members for sealing lubricant oil within bearing element raceway are disposed between the inner circumferential surface of the roller and an inner circumferential surface of the thrust bearing annular member. The sealing members slidably contact but are not deformed by the inner circumferential surface of the roller.
    • 输送链,其构造为防止润滑油向外部泄漏。 输送机链条包括多个轴承元件,其可操作以在套筒的外周面和辊的内周面之间的滚道中旋转。 一对左右推力轴承环形构件压配合到衬套的外周面上,并且位于内连接板的内侧表面和轴承元件的向外端面之间。 用于密封轴承元件滚道内的润滑油的环形密封件设置在滚子的内圆周表面和止推轴承环形构件的内圆周表面之间。 密封构件可滑动地接触,但不会被辊的内周面变形。
