    摘要: Carboxylic acid ester functionalised derivatives of polymeric compounds containing residual carbon-carbon double bonds, for example polyisobutylenes and ethylene-based copolymers and terpolymers, are produced by reacting the polymeric compound with carbon monoxide and an alcohol in the presence of a protonic acid and as catalyst (a) at least one of the metals palladium, rhodium, ruthenium, iridium and cobalt in elemental or compound form and (b) a copper compound. In a modification of the invention carboxylic acid derivatives are produced by replacing the alcohol reactant with less than 8 mole equivalents, based on the polymeric compound, of water.

    摘要: Alkylene glycols are prepared by reaction of an alcohol with formaldehyde and an organic peroxide having a formula R-O-O-R 1 where R and R' are independently either alkyl or aralkyl groups containing 3 to 12 carbon atoms. The reaction is carried out in the presence of electromagnetic radiation which is able to decompose the organic peroxide. The alcohol used in this process is either methanol, a secondary alcohol or a mixture thereof.

    摘要: A sealing assembly comprises three non-compressible and relatively movable members, the first and second members (3,2) having a first elastomeric sealing element (5) located between them, the second (2) and third members (1) having a second elastomeric element (6) located between them to urge the second member away from the third member and towards the first member. Spaces are provided between the second and third members and are occupied by an elastomeric spring (8) biassed to urge the second member away from the first member and a metallic spring (7) biassed to urge the second member towards the first member. The force exerted by the elastomeric spring is greater than and opposite to that exerted by the metallic spring.
