    • Tires having white sidewalls are very popular in the United States and Canada. Tires having white lettering thereon are also very popular. This invention discloses a process for preparing such tires having decorative appliques thereon. By practicing the process of this invention, tires having better uniformity can be built at lower costs than when standard tire building techniques are utilized. This invention specifically relates to a method of preparing a pneumatic rubber tire having a decorative design on the sidewall thereof which comprises (a) applying the decorative applique to the sidewall of an uncured tire and (b) curing the tire; wherein the decorative applique is comprised of from about 25 weight percent to about 75 weight percent syndiotactic 1,2-polybutadiene having a melting point which is within the range of about 70.degree. C. to about 160.degree. C. and from about 25 weight percent to about 75 weight percent of at least one polydiene rubber which is cocurable with said syndiotactic 1,2-polybutadiene, sulfur, zinc oxide and at least one pigment or colorant.
    • 具有白色侧壁的轮胎在美国和加拿大非常受欢迎。 具有白色刻字的轮胎也非常受欢迎。 本发明公开了一种在其上制备具有装饰贴花的轮胎的方法。 通过实践本发明的方法,可以以比使用标准轮胎成型技术更低的成本来建造具有更好的均匀性的轮胎。 本发明具体涉及一种制造在其侧壁上具有装饰设计的气动橡胶轮胎的方法,其包括(a)将装饰贴花施加到未硫化轮胎的侧壁上,以及(b)固化轮胎; 其中装饰贴花由约25重量%至约75重量%的间同立构1,2-聚丁二烯组成,间同立构1,2-聚丁二烯的熔点在约70℃至约160℃的范围内,约25重量% 至约75重量%的至少一种可与所述间同立构1,2-聚丁二烯,硫,氧化锌和至少一种颜料或着色剂共聚的聚二烯橡胶。
