Abstract
Low molecular weight olefin resins are blended with small amounts of high molecular weight olefin resins and the blends are chlorinated or chlorosulfonated. Melt and film strengths of the resultant low molecular weight chlorinated and chlorosulfonated resins are thereby increased sufficiently to enable recovery by means of methods which require film or strand formation. The chemical properties and solution characteristics of the blends are substantially maintained compared to those of the low molecular weight chlorinated resins themselves.
