High cis butadiene.This company is said to have succeeded in the development of a synthesis technology for a high cis butadiene butadiene (by  t'ədī`ēn), colorless, gaseous hydrocarbon. There are two structural isomers of butadiene; they differ in the location of the two carbon-carbon double bonds in the rubber that chemically bonds with silica at its molecular chain end. The rubber compound used in tires is a complex mixture of polymers such as natural rubber and synthetic rubber synthetic rubber: see rubber. , reinforcing fillers such as carbon black and silica, together with other ingredients. One of the polymers, high cis butadiene rubber (also known as cis BR), is said to have outstanding low-temperature flexibility, abrasion resistance and flex fatigue resistance on account of its microstructure mi·cro·struc·ture n. The structure of an organism or object as revealed through microscopic examination. microstructure Noun a structure on a microscopic scale, such as that of a metal or a cell . Silica, on the other hand, is said to display excellent performance in wet grip, and also reduces rolling resistance Rolling resistance, sometimes called rolling friction or rolling drag, is the resistance that occurs when an object such as a ball or tire rolls. It is caused by the deformation of the wheel or tire or the deformation of the ground. . As a result, efforts are said to have focused on combining these two materials, but there was a limitation coming from poor affinity of cis BR with silica. The company has developed two new technologies to solve this. NanoPro-Tech (nanostructure-oriented properties control technology) is the generic name generic name n. 1. The official nonproprietary name of a drug, under which it is licensed and identified by the manufacturer. 2. for the technology to control the affinity between the filler and the polymer at will.
