サイドで加硫する方法は良く知られている。More specifically, it is a novel vulcanization method characterized by using triacryloyl-S-triazine (TAF) or a combination of TAF and triallyl isocyanurate (TAIC) when vulcanizing a hydrocarbon elastomer with an organic peroxide. Concerning the sulfur method. Traditionally, hydrocarbon elastomers, especially ethylene-propylene copolymers (EPR) or ethylene-propylene-diene terpolymers (EP
A method of vulcanizing EPR (hereinafter referred to as EP elastomer) with an organic peroxide such as dikymyl peroxide is well known.

至つた。Furthermore, in such known vulcanization methods, certain polyfunctional monomers, such as ethylene dimethacrylate or triallyl cyanurate, are used in combination for the purpose of increasing vulcanization efficiency and completing vulcanization quickly. , or E
It is also known to use a small amount of sulfur in the vulcanization of PDM. However, the above-mentioned known methods are not necessarily satisfactory in achieving the early completion of vulcanization, which is the objective, and have the disadvantage that it is difficult to notice any improvement in the physical properties of the obtained vulcanizate. The present inventor has repeatedly studied a new method for vulcanizing EP elastomers in order to overcome the drawbacks of such conventional methods, but when using an organic peroxide as a vulcanizing agent for the EP elastomers, By using TAF or TAF and TAIC,
The present inventors have discovered that it is possible to achieve both early completion of vulcanization and improvement of the resulting vulcanized physical properties, and have completed the present invention.

TAIC does not need to be a pure product; commercially available purity (approximately 90%) is sufficient for its purpose, and when only TAF is used, it is 0.1 to 10 parts per 100 parts of EP elastomer. , preferably 0.1 part or more and less than 5 parts, particularly 0.5 part or more and less than 5 parts, and when TAF and TAIC are used together, each 0.1 part
~10 parts, preferably 0.5 to 3 parts and TAF/TA
The weight ratio of IC is 20/1 to 1/10, preferably 10/1
It is used in the range of 1 to 1/5.
