Abstract
A dihalocyclopropane functional multi-component copolymer is produced by reacting olefin bond units contained in the side chain or in the cyclic group in the main chain of a multi-component copolymer with dihalocarbene generated from halogenated hydrocarbon in the presence of a cation surfactant catalyst by using an alkali aqueous solution. The dihalocyclopropane functional multi-component copolymer has an excellent compatibility as a polymer to be blended with the general purpose rubber and as a halogenated rubber series industrial material.
