PROBLEM TO BE SOLVED: To provide isoprene oligomer and polyisoprene in which an only terminal part of the molecule is modified substantially, a rubber composition comprising the isoprene oligomer and/or the polyisoprene, and a pneumatic tire the rubber composition of which is used in each member such as a tread and a side wall.SOLUTION: The present invention provides isoprene oligomer in which at least one atom or atomic group included in I-I part of the following formula (1) is substituted with a sulfur atom or an atomic group containing a sulfur atom, and polyisoprene having the isoprene oligomer at the terminal part of a polymer chain. In the formula (1), n is an integer of 1 to 10, m is an integer of 1 to 30, and Y is a hydroxyl group, a formyl group, a carboxyl group, an ester group, a carbonyl group or a diphosphate group.
【課題】実質的に分子の末端部分のみに変性が加えられたイソプレンオリゴマー、ポリイソプレンの提供。また、該イソプレンオリゴマー及び／又は該ポリイソプレンを配合したゴム組成物、並びに該ゴム組成物をタイヤの各部材（トレッド、サイドウォール等）に用いた空気入りタイヤの提供。【解決手段】下記式（１）中のＩ−Ｉ部分に含まれる原子又は原子団の少なくとも１つが、硫黄原子又は硫黄原子を含む原子団により置換されているイソプレンオリゴマー。前記イソプレンオリゴマーをポリマー鎖の端部に有するポリイソプレン。（ｎは１〜１０の整数，ｍは１〜３０の整数、Ｙは水酸基、ホルミル基、カルボキシル基、エステル基カルボニル基または二リン酸基）【選択図】なし
