Patent EP-0437279-A2 (EP)
Inventor: ABAYASEKARA DILIP RANJITHA
IPC: C08G69/14
Filed: 1991-01-11
Abstract: Graft copolymers of ε-caprolactam are made by a process in which ε-caprolactam is polymerized in the presence of a copolymer of an aliphatic acrylate and an ethylenically unsaturated carboxylic acid, such as n-butyl-acrylate and acrylic acid. Such grafted polymers which have nylon-6 side chains grafted onto the acrylate polymer backbone are useful as hot melt adhesives. In the process for preparing these polymers, the backbone polymer is formed initially by solution polymerizatlon at a moderate temperature and the ε-caprolactam is then added and the temperature increased in the presence of an acidic catalyst. ε-Caprolactam can be used as the solvent in the polymerizatlon of the backbone polymer.

Abstract: An electronically controlled transmission in which a shift actuator for driving a sleeve of a roller synchro mechanism and a throttle actuator for an engine are electronically controlled. The shift actuator is comprised of a drum type actuator of a simple structure comprising a shift drum and a shift fork. The use of the roller synchro mechanism ensures that only a small driving force for the shift drum is required, which makes it possible to provide a reduction in size of the shift actuator. In addition, a shift lever for operating a shift switch for producing the shifting instruction signal is mounted on either left or right side of the steering wheel. This ensures that the shifting-up and shifting-down signals can be produced by one of the driver's hands, leading to an improvement in operability of the shift lever.
