    摘要： This invention relates to a process for producing substituted acylating agents by the reaction of an enophile with an ene by the thermal route wherein (a) the molar ratio of the enophile to the ene is at least 3:1 and (b) the reaction pressure is raised to above 20 psig an least after addition of the enophile reaction to the reaction is completed and is maintained substantially constant until at least 80% of the ene reactant has been converted to the corresponding acylating agent. The agents so produced are substantially free of chlorine and can be further reacted with an amine or a hydroxy compound to form a derivative which can be used as an additive for a lubricating oil or a fuel.

    摘要： This invention relates to a process for making substituted acylating agents by the reaction of an enophile containing at least one carboxyl group with a polyolefin selected from polypropylene and poly(iso)butene. To the reaction mixture is added an at least (a)one olefin of the formula (R)(R.sup.1).C.dbd.C.(R.sup.2)(R.sup.3) wherein at least one of R, R.sup.1, R.sup.2 and R.sup.3 is hydrogen and at least one of the other three is (i) an alkyl group having at least 3 carbon atoms or (ii) at least one of R.sup.2 and R.sup.3 together with R.sup.1 forms a cycloaliphatic ring such that the olefin has at least 5 carbon atoms in a linear hydrocarbyl chain, or, (b) one adduct of said olefin of formula (I) with the reactant enophile. The products of the reaction have a substantially reduced amount of resin.

    摘要： This invention relates to a process for functionalising synthetic hydrocarbyl polymers having at least one olefinic group by (i) reacting at elevated temperature the synthetic hydrocarbyl polymer with an alkyne compound substituted with at least one electron withdrawing --C(O)R or a --CN group so that the olefinic group in the polymer reacts with the alkyne group of the alkyne compound to form an intermediate and (ii) reacting the intermediate from step (i) above with a nucleophile to form a functionalised hydrocarbyl polymer. The functionalised polymers are useful as additives for lubricating oils and fuels.

    摘要： This invention relates to a process for the production of polyolefin 1,3-diols, said process comprising (a) reacting a polyolefin epoxide with a borane or a precursor thereof in a borane-co-ordinating solvent to form an intermediate borane ester, and (b) subjecting the intermediate borane ester so formed in (a) to an alkaline oxidative hydrolysis to form the polyolefin diol. 1,3-diols of polyolefins, especially those of atactic polypropylene and poly(iso)butene, having a --C(CH.sub.3).dbd.CH.sub.2 end group are novel compounds. These diols can be converted into useful products such as e.g. the corresponding carboxylic acids, diamines or hydroxy-amines, or polyethers which are useful as such or as intermediates for producing lube oil and fuel additives.
