  • Method for preparing 1-chloro-1-iodoethane
    Patent number: 5345018
    Abstract: The present invention relates to a method of synthesizing 1-chloro-1-iodoethane by reacting hydrogen iodide with vinyl chloride monomer in the presence of an iodine containing catalyst under certain specified conditions. The resulting product of the reaction is a high yield, high purity 1-chloro-1-iodoethane. This 1-chloro-1-iodoethane is useful as a chain transfer agent in the polymerization of vinyl chloride monomer in a process which mimics a pseudo-living radical polymerization.
