摘要
The work described in this paper was aimed at developing improved carcass and trend stocks that can be used to upgrade the durability of polyester cord tires in severe laboratory wheel tests. Carcass stocks were developed with acceptable properties and good adhesion to polyester tire cords after severe heat aging in laboratory tests. In a variety of wheel tests 2-ply tires with cords of Dacron polyester containing amine-free tread and carcass stocks showed highly improved durability (180-440 per cent) compared to control tires made with stocks containing amines. These tests clearly illustrated the additive benefits of combining an improved polyester with stocks having reduced amine content.
