The present invention discloses tire sidewall rubber. The tire sidewall rubber according to the present invention includes novel EPDM rubber that is mixed with natural rubber or synthetic rubber, which is raw material rubber, wherein the EPDM rubber is represented by chemical formula 1. According to the present invention, the crosslinking performance and ozone resistance of rubber for tire sidewall can be improved, and in addition, the ozone resistance of sidewall rubber can be further improved by using novel EPDM instead of synthetic rubber in the mixture of natural rubber and synthetic rubber.

    본 발명은 타이어 사이드월고무를 개시한다. 본 발명에 따르는 타이어 사이드월고무는 원료고무인 천연고무 또는 합성고무에 혼합하여 사용하는 신규한 EPDM 고무를 포함하는 타이어 사이드월고무에 있어서, 상기 EPDM 고무는 하기 화학식 1로 표기되는 것을 특징으로 하는데 이에 의할 때, 타이어 사이드월용 고무의 가교성능 및 내오존성능을 향상시키고 더하여 천연고무와 합성고부의 혼합에서 합성고무 대신 신규한 EPDM을 사용하여 사이드월고무의 내오존성 성능을 더 개선시킬 수 있다.
