Rubber compounds comprising rubber and propylene-alpha-olefin-diene (PE (D) M) polymers may be used in tire related articles (e.g., tire sidewalls, inner tubes, and inner liners). Such a rubber compound may include from about 5 phr to about 50 phr of a PE (D) M polymer including from about 65 wt% to about 99.5 wt% propylene, from about 0.5 wt% to about 35 wt% non-propylene alpha-olefin, and from 0 wt% to about 20 wt% diene, the wt% based on the weight of the PE (D) M polymer, and from about 50 parts per 100 parts of rubber (phr) to about 95 phr of rubber, the weight of the PE (D) M polymer being about 50 parts per 100 parts of rubber (phr). The rubber comprises one selected from the group consisting of halogenated isobutylene-based rubber, natural rubber, polyisoprene rubber, poly (styrene-co-butadiene) rubber, polybutadiene rubber, poly (isoprene-co-butadiene) rubber, styrene-isoprene-butadiene rubber, butyl rubber, star-branched butyl rubber, and one selected from the group consisting of halogenated isobutylene-based rubber, natural rubber, polyisoprene rubber, poly (styrene-co-butadiene) rubber, polybutadiene rubber, poly (isoprene-co-butadiene) rubber, styrene-isoprene-butadiene rubber, and star-branched butyl rubber. An isobutylene-isoprene rubber, a poly (isobutylene-co-alkylstyrene), a halogenated isobutylene-based rubber, a polychloroprene rubber, a nitrile rubber, and any combination thereof.

    包含橡胶和丙烯‑α‑烯烃‑二烯(PE(D)M)聚合物的橡胶配混物可用于轮胎相关制品(例如轮胎侧壁、内管和内衬)。此种橡胶配混物可以包含:约5phr至约50phr的包含约65wt%至约99.5wt%丙烯、约0.5wt%至约35wt%非丙烯的α‑烯烃和0wt%至约20wt%二烯的PE(D)M聚合物,所述wt%基于所述PE(D)M聚合物的重量,和约50份/100份橡胶(phr)至约95phr的橡胶,所述橡胶包含选自以下物质中的一种:基于卤化异丁烯的橡胶、天然橡胶、聚异戊二烯橡胶、聚(苯乙烯‑共聚‑丁二烯)橡胶、聚丁二烯橡胶、聚(异戊二烯‑共聚‑丁二烯)橡胶、苯乙烯‑异戊二烯‑丁二烯橡胶、丁基橡胶、星形支化丁基橡胶、异丁烯‑异戊二烯橡胶、聚(异丁烯‑共聚‑烷基苯乙烯)、基于卤化异丁烯的橡胶、聚氯丁二烯橡胶、丁腈橡胶及其任何组合。
