Traditionally, natural rubber (NR) and synthetic rubbers, such as styrene-butadiene rubber (SBR), polybutadiene rubber (BR), polyisoprene rubber (IR) and nitrile rubber (NBR), have a high degree of specific soft unsaturation. Various vulcanization accelerators are used for sulfur vulcanization of highly unsaturated rubbers, most of which are N-cyclohexylbenzothiazyl-2-sulfenamide (CBS) and N-t--/
Sulfenamide derivatives such as tilbenzothiazylsulfenamide.

However, although such vulcanization accelerators are effective as vulcanization accelerators for these rubbers alone, they are not effective for these highly unsaturated rubbers and ethylene-propylene-nonconjugated diene ternary copolymer rubbers. There is a problem with sulfur co-vulcanization with low unsaturation rubber such as (EPDM) that it cannot be used because the tensile properties of the resulting rubber are significantly reduced. It has been desired to develop a versatile vulcanization accelerator that can be used not only as an accelerator but also as a vulcanization accelerator for co-vulcanization of a highly unsaturated rubber and a low unsaturated rubber.

For this reason, the present inventors solved the above problem,
A study was conducted to develop a vulcanization accelerator that can be used not only for the vulcanization of each rubber alone, but also for the co-vulcanization of a highly unsaturated rubber and a low unsaturated rubber. As a result, it was discovered that a maleimide or isomaleimide derivative having a specific structure has an extremely excellent effect on the above object, and the present invention was achieved.

Table 4 From the results in Table 4, it can be seen that the co-vulcanized rubber using modified EPDM has lower tensile strength and elongation than the co-vulcanized rubber using unmodified EPDM, although the modulus is almost the same. It can be seen that the value is large, indicating that vulcanization is more homogeneous.
