The invention relates to an isoprene oligomer that contains a trans structural moiety and a cis structural moiety, which can be represented by the following formula (1), wherein at least 1 atom or group in the trans structural moiety is replaced by another atom or group. The invention also relates to a polyisoprene, which is biosynthesized using the isoprene oligomer and isopentenyl diphosphate. Further, this invention provides a rubber composition comprising the isoprene oligomer and/or the polyisoprene, and a pneumatic tire, including tire components (e.g., treads and sidewalls) formed from the rubber composition.
wherein n represents an integer from 1 to 10; m represents an integer from 1 to 30; and Y represents a hydroxy group, a formyl group, a carboxy group, an ester group, a carbonyl group, or a group represented by the following formula (2):
该发明涉及一种含有反式结构基团和顺式结构基团的异戊二烯寡聚物,可以用以下公式(1)表示,其中反式结构基团中至少有1个原子或基团被另一个原子或基团取代。该发明还涉及一种聚异戊二烯,它是使用异戊二烯寡聚物和异戊二烯二磷酸盐生物合成的。此外,该发明提供了一种橡胶组合物,包括异戊二烯寡聚物和/或聚异戊二烯,以及一种充气轮胎,其中轮胎组件(例如胎面和侧壁)由该橡胶组合物形成。
其中n表示1到10之间的整数;m表示1到30之间的整数;Y表示一个羟基、一个甲酰基、一个羧基、一个酯基、一个酰基或由以下公式(2)表示的基团。
