Abstract: Polyisobutylene is prepared from a mixed C.sub.4 hydrocarbon feedstream using an AlCl.sub.3 --HCl catalyst system wherein the HCl is introduced separately into the feedstream to form organochloride in the feedstream. Polymer product having a very narrow molecular weight distribution is obtained over the Mn range of 700 to 3,000. Dispersants derived from this polyisobutylene exhibit substantially improved performance in lubricating oil compositions.

Abstract: Polymerization slurries of elastomeric isoolefin homopolymers and copolymers, such as butyl rubber, in diluents such as methyl chloride are effectively stabilized against agglomeration of polymer particles through addition of minor proportions of an hydrogenated preformed copolymer stabilizer having both a lyophobic and a lyophilic portion. The chemical and structural nature of the lyophobic and lyophilic portions which comprise the copolymer stabilizer are significant in determining the extent and method of hydrogenation for production of the most effective stabilizer. Agglomeration of polymer products is effectively prevented, yielding a number of significant processing advantages. The process is especially adaptable to the production of isobutylene-isoprene butyl rubber.

Abstract: High molecular weight polybutenes having a viscosity SSU above 1,000,000 at 210.degree. F. are produced by using a three-component catalyst system containing an alkyl aluminium halide, tertiary butyl halide and a metal halide selected from SnCl.sub.4, SnBr.sub.4, TiCl.sub.4, and TiBr.sub.4. The reaction phase is homogeneous and the catalyst components are added as a solution in an inert solvent. The polyisobutene product so produced are useful additives for oil, adhesives and mastics.

Abstract: Novel telechelic halogenated polymers of cationically polymerizable olefin monomers are formed carrying from 2 to about 6 terminal halogens. The telechelic halogenated polymers are formed by reacting the monomer with an initiator transfer agent, carrying at least two tertiary halogens, and under cationic polymerization conditions. Additionally, novel thermoplastic elastomer block copolymers are formed from these telechelic halogenated polymers by reacting the latter with vinyl aromatic monomers in the presence of a coinitiator.
