Title:
ISOPRENE OLIGOMER, POLYISOPRENE, PROCESSES FOR PRODUCING THESE MATERIALS, RUBBER COMPOSITION, AND PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2012/008298
Kind Code:
A1
Abstract:
The present invention relates to: an isoprene oligomer composed of a trans structural moiety represented by formula (1) and a cis structural moiety, wherein at least one of atoms or groups of atoms contained in the trans structural moiety is substituted by another atom or another group of atoms; and a polyisoprene which is biosynthesized from the isoprene oligomer and an isopentenyl diphosphate. The present invention also provides: a rubber composition containing the isoprene oligomer and/or the polyisoprene; and a pneumatic tire in which the rubber composition is used in a part (e.g., a tread, a side wall) of the tire.
(In formula (1), n represents an integer of 1-10; m represents an integer of 1-30; Y represents a hydroxy group, a formyl group, a carboxy group, an ester group, a carbonyl group or a group represented by formula (2).)
