    • The hyperbranched polymers are at least one anhydrosugar-related compound selected from the dianhydrosugar alcohol [1]: (wherein R is hydrogen atom or a hydrocarbon group having from 1 to 30 carbon atoms, provided that nR's are equal to or different from one another and at least one R of nR's is hydrogen atom, and symbol n is an integer from 1 to 10) and the anhydrosugar alcohol [2]: (wherein each of R1, R2, R3 and R4 is hydrogen atom or a hydrocarbon group having from 1 to 30 carbon atoms; provided that R1, mR2's, pR3's and R4 are equal to or different from one another and at least one R2 or R3 of said mR2's and pR3's is hydrogen atom, respectively; and symbol m is zero (0) or an integer from 1 to 20 and symbol p is an integer from 1 to 20, provided that symbol m+p is an integer from 1 to 20)or at least one anhydrosugar-related compound selected from the dianhydrosugar alcohol [1] and/or the anhydrosugar alcohol [2] with at least one sugar compound selected from the anhydrosugar as represented by the general formula [3], [4], [5], [6] or [7].The hyperbranched polymers are readily prepared by polymerizing the dianhydrosugar alcohol or the anhydrosugar [1] or [2] or the dianhydrosugar alcohol or the anhydrosugar [1] or [2] together with the anhydrosugar in the presence of a cationic or anionic initiator.
    • 超支化聚合物是选自二脱水葡萄糖醇[1]中的至少一种脱水糖相关化合物:其中R是氢原子或具有1至30个碳原子的烃基,条件是nR彼此相同或不同; nR的至少一个为氢原子,符号n为1〜10的整数)和脱水葡萄糖醇[2] :(式中,R 1,R 2,R 3,R 4分别为氢原子或1个 至30个碳原子;条件是R1,mR2,pR3和R4彼此相同或不同,并且所述mR2和pR3的至少一个R2或R3分别为氢原子;符号m为零(0)或 1〜20的整数,符号p为1〜20的整数,条件是符号m + p为1〜20的整数)或至少一种选自二脱水糖醇[1]和/或 具有至少一种选自脱水葡萄糖的糖化合物的脱水葡萄糖醇[2]作为r 由通式[3],[4],[5],[6]或[7]表示。 通过在阳离子或阴离子引发剂的存在下,将二脱水糖醇或脱水葡萄糖[1]或[2]或二脱水糖醇或脱水葡萄糖[1]或[2]与脱水葡萄糖一起聚合,可以容易地制备超支化聚合物。

    • In a movable guide for transmission device in which a guide body is formed from a synthetic resin and comprises a chain-contacting shoe and a plate-receiving portion formed as a unit with the shoe on the back side thereof, the plate-receiving portion has plural, longitudinally extending slots, each receiving a reinforcing plate. The plural reinforcing plates improve the bending rigidity, toughness, strength and wear properties of the guide, prevent falling down of the guide and guide torsion, ensure stable travel of the chain, and prevent running of the chain off the guide in a widthwise direction. Improved compactness of the guide and of the overall mechanism, is made possible by the use of plural plates. The plates can be connected to one another by a tensioner-contacting portion, formed as a unit with the plates.
    • 在一种用于传动装置的可移动导向件中,其中引导体由合成树脂形成,并且包括链接接触靴和在其后侧形成为鞋的单元的板接收部,板接收部具有 多个纵向延伸的槽,各自容纳加强板。 多个加强板提高了引导件的弯曲刚度,韧性,强度和磨损性能,防止了引导件的引导和引导扭转,从而确保链条的稳定行进,并且可以防止链条沿横向方向从引导件的运动。 引导件和整个机构的改进的紧凑性可以通过使用多个板来实现。 板可以通过与板形成为一体的张紧器接触部分彼此连接。
