ABSTRACT
Butlerov and Gorianov are attributed with preparing the first polymers of isobutylene in the 1800’s. This followed work by Berthelot and others who studied the polymerisation of various olefins using Friedel-Crafts catalysis systems [1]. During the 1930’s commercial processes for the manufacture of solid polyisobutylene rubbers were introduced first in Germany [2] and then in the United States [3]. It was not until later, in the 1940’s and 1950s, that commercial routes were developed for the preparation of liquid polybutenes by Chevron [4], Standard Oil of Indiana [5], and the Cosden Petroleum Corporation [6] in the United States.
