    • The present block copolymer contains a structural unit (A) derived from a compound represented by the general formula (I): CH.sub.2 .dbd.CR.sub.1 COOR.sub.2 R.sub.f, and also contains a structural unit (B) consisting of a polymer moiety represented by at least one of the structural formulae (III) and (IV) and another polymer moiety derived from a compound represented by the general formula (II): CH.sub.2 .dbd.CR.sub.3 R.sub.4. For preparing the above block copolymer, a block copolymer consisting of the structural unit (A) derived from a compound represented by the general formula (I): CH.sub.2 .dbd.CR.sub.1 COOR.sub.2 R.sub.f and the structural unit (B1) derived from a compound represented by the general formula (II): CH.sub.2 .dbd.CR.sub.3 R.sub.4 and a compound represented by the general formula (V): CH.dbd.CR.sub.6 COO(R.sub.9).sub.t H are reacted with a compound represented by the general formula (VI): R.sub.10 COCl to allow a dehydrochlorination reaction to take place. Thus, an unsaturated group and fluorine containing block copolymer having excellent water and oil repellent properties and excellent sensitivity to activation energy rays can be prepared. The block copolymer is utilized as a surface modifier for activation energy-curing resins.
    • 本发明的嵌段共聚物含有由通式(I)表示的化合物衍生的结构单元(A):CH2 = CR1COOR2Rf,并且还含有由结构单元(B)构成的结构单元, 式(III)和(IV)表示的另一聚合物部分和由通式(II)表示的化合物衍生的另一聚合物部分:CH 2 = CR 3 R 4。 为了制备上述嵌段共聚物,由由通式(I)表示的化合物衍生的结构单元(A):CH 2 = CR 1 COOR 2 R f和由通式(I)表示的化合物衍生的结构单元(B1) (II):CH 2 = CR 3 R 4和由通式(V)表示的化合物:CH = CR 6 COO(R 9)t H与通式(VI)表示的化合物:R 10 COCl反应,以进行脱氯化氢反应。 因此,可以制备具有优异的防斥油性和对激活能量射线具有优异敏感性的不饱和基团和含氟嵌段共聚物。 嵌段共聚物用作活化能量固化树脂的表面改性剂。

    • A rear wheel is provided with a steering characteristic such that a vehicle runs on a cornering path with a longitudinal center line of the vehicle substantially aligned with a tangential line of the cornering path throughout cornering movement. A fail judge device is provided for judging when a rear wheel steering device failure is present in light of a criterion based on a rear wheel steering. A criterion change device is also provided for changing the criterion between a transitional cornering condition, in which the vehicle is in an initial stage of a cornering movement just after a steering operation and before a cornering force acting on the vehicle body reaches a substantial value, and a steady cornering condition, in which the cornering force has reached the substantial value. A reverse phase control can be properly performed without failure judgment. This assures that a desirable driving feeling is provided for the driver when cornering as well as improved safety.
    • 后轮设置有转向特性,使得车辆在转弯路径上行驶,其中车辆的纵向中心线在转弯运动时基本上与转弯路径的切线对齐。 提供了一种故障判断装置,用于根据基于后轮转向的标准判断何时存在后轮转向装置故障。 还提供了一种标准更换装置,用于在转向操作之后的转弯运动的初始阶段和作用在车体上的转弯力达到实质值的过渡转弯状态之间改变标准, 以及一个稳定的转弯条件,其中转弯力已达到实质价值。 无故障判断可正确执行反相控制。 这确保了在转弯时为驾驶员提供期望的驾驶感觉以及改进的安全性。
