Abstract: Vulcanizable, elastomeric copolymers of vinyl ethers and cyclic polyenes, which have a molecular weight above 50,000 and a vinyl ether content in excess of 80%, are prepared by reacting an alkyl vinyl ether such as vinyl isobutyl ether with a conjugated cyclic diolefin wherein both double bonds are endocyclic or with a cyclic diolefin or triolefin having a system of conjugated double bonds, at least one of which is endocyclic, in the presence of a Friedel-Crafts catalyst and a solvent of low or high polarity; the nature and state of the obtained copolymer being controllable by the respective concentrations of the reactants and the polarity of the reaction medium.

Abstract: A process is disclosed whereby aromatic hydrocarbons such as benzene, toluene and xylene are separated with high selectivity from mixtures in which they are contained through extraction and/or extractive distillation with the aid of a solvent mixture including morpholine and another solvent such as an oxygen containing derivative of morpholine and water, e.g. morpholinewater, morpholine-N-formyl morpholine and morpholine-N-formyl morpholine-water, in three main steps: (1) concentration of nonaromatic hydrocarbons to produce a stream free from aromatics; (2) purification of aromatics dissolved in rich solvent; and (3) recovery of the aromatics from the rich solvent.
