    • Substantially gel-free, high unsaturation copolymers of isobutylene and isoprene and high unsaturation terpolymers of isobutylene, isoprene and cyclopentadiene having a number average molecular weight of at least about 90,000 and a mole percent of unsaturation of at least 5% and the process for preparing said polymers which comprises carrying out the polymerization in a homogeneous phase, introducing to the system either an aluminum halide in a soluble form or a hydrocarbylaluminum dihalide and carrying the reaction out at a temperature of less than about -100.degree. C. Vulcanizable compositions are formed from the co- and ter- polymers by reacting them with a vulcanizing amount of sulfur donor and a delayed action accelerator, wherein the vulcanized compositions can be extended with fillers, non-polar process oils and rubbers.

    • The present invention relates to a process for the encapsulation of a solid substrate with a neutralized sulfonated polymer, which comprises the steps of: (a) forming a solution of a non-conjugated, diene polymer in a solvent selected from the group consisting of aliphatic, aromatic hydrocarbons and mixtures thereof; (b) contacting the solution of the unsaturated polymer with a sulfonating agent at a sufficient temperature and for a sufficient period of time to form a solution of a sulfonated polymer containing free acid; (c) forming a solution of a base selected from the group consisting of alkali metal hydroxides and mixtures thereof in a mixtrue of an aliphatic alcohol and a hydrocarbon, the hydrocarbon being selected from the group consisting of aliphatic and aromatic hydrocarbons and mixtures thereof; (d) adding the solution of base to the solution of sulfonated polymer in an amount sufficient to neutralize the polymer and the free acid, thereby forming a coating solution; (e) contacting the solid substrate with the coating solution while removing the solvent therefrom, thereby forming an encapsulated substrate. In a preferred embodiment, the solvent removed during step (e) is recovered and distilled to separate the solvent into at least two fractions, a fraction containing substantially hydrocarbon and an alcohol containing fraction. The separated solvents are then recycled to dissolve the polymer in step (a) and to dissolve the base in step (c).
    • 本发明涉及用中和的磺化聚合物包封固体基质的方法,其包括以下步骤:(a)在选自脂肪族的溶剂中的溶剂中形成非共轭二烯聚合物的溶液 ,芳族烃及其混合物; (b)在足够的温度下将不饱和聚合物的溶液与磺化剂接触足够的时间以形成含有游离酸的磺化聚合物的溶液; (c)在脂族醇和烃的混合物中形成选自碱金属氢氧化物及其混合物的碱的溶液,所述烃选自脂族和芳族烃及其混合物; (d)将碱溶液以足以中和聚合物和游离酸的量向磺化聚合物溶液中加入,从而形成涂布溶液; (e)将固体基质与涂布溶液接触,同时从其中除去溶剂,由此形成封装的基材。 在优选的实施方案中,回收步骤(e)中除去的溶剂并蒸馏以将溶剂分离成至少两个馏分,基本上含有烃和含醇的馏分。 然后将分离的溶剂再循环以在步骤(a)中溶解聚合物并在步骤(c)中溶解碱。
