    摘要: Polybutene is prepared from a mixed C₄ hydrocarbon feedstream using an organo-aluminum/HCl catalyst system wherein the HCl is introduced separately into the feedstream to form organochloride in the feedstream. Polybutene product having a very narrow molecular weight distribution is obtained over the M n range of 700 to 3,000. Dispersants derived from this polybutene exhibit substantially improved performance in lubricating oil compositions.

    摘要: A novel product of the polymerization of butene-1 is highly stereoregular but nevertheless has low crystallinity and has properties of a thermoplastic elastomer.
    This elastomeric polybutylene is the total product. Its elastomeric qualities lie between those of plasticized vinyl polymers and conventional vulcanized rubbers.
    The butene-1 polymers may be compounded with extenders and fillers for use as molded or extruded elastomeric product or may be used without plasticizer addition in place of flexible vinyl polymers, such as highly plasticized poly(vinylchloride) (PVC).
