Polybutadiene Rubber (BR)

Abstract

Butadiene-l,3 together with solvent and catalyst are first of a series of polymerisation reactors, polymerises exothermically. File: G54 ISle 3513 mixed and passed to the where the butadiene When oil extended types of BR are produced, oil is metered into the polymer cement and passed to steam strippers for converting the cement to a slurry. Vapours from the stripping are condensed and recycled for purification.
