✦ Synopsis

Chemical modifications to either rubber or nylon have been performed in order to assess the effect on rubber-to-nylon adhesion. The rubber has been modified by epoxidizing up to 60% of the double bonds present. The nylon was modified by reacting the surface with either sebacoyl chloride or phosphorus pentachloride. The adhesion of modified rubber-to-nylon and modified nylon-to-rubber was measured by means of a peel test. The results show that significant improvement of the adhesion can be achieved. Some experiments were performed using vulcanizates of the rubbers, and coated nylon tyre-cord, as in tyre manufacture. The adhesion of the vulcanized epoxidized rubbers at 363 K, showed less deterioration with time than the conventional tyre vulcanizate.
