    摘要: A process for polymerizing unsaturated fatty acids comprises heating the fatty acids in the presence of a catalytic proportion of an unactivated clay and water. The product polymerizate is distilled to separate unreacted monomer acids which are separately polymerized under similar conditions. Higher overall polymer yields are obtained.

    摘要: Compounds are described of the formula ##STR1## in which R.sup.1 is COOR.sup.5, CONHR.sup.5, cyano, 5-tetrazolyl or R.sup.6, where R.sup.5 is hydrogen or C.sub.1-8 alkyl and R.sup.6 is phenyl or naphthyl, the phenyl or naphthyl group being optionally substituted by one or more group selected from halogen, C.sub.1-6 alkyl, C.sub.1-4 alkoxy, hydroxy, benzyloxy, nitro, trifluoromethyl, carboxyl, C.sub.1-4 alkylsulphinyl, C.sub.1-4 alkylsulphonyl, N(R.sup.5).sub.2, NHCOR.sup.5 and SR.sup.5 ; R.sup.2 is R.sup.6 or --CH.dbd.CH--R.sup.6 when R.sup.1 is COOR.sup.5, CONHR.sup.5, cyano or 5-tetrazolyl, or R.sup.2 is --CH.dbd.CH--R.sup.6 when R.sup.1 is R.sup.6 ; R.sup.3 is hydrogen, C.sub.1-6 alkyl, halogen, hydroxy or --OCH.sub.2 R.sup.6 ; and R.sup.4 is hydrogen, C.sub.1-6 alkyl or halogen; and salts thereof. The compounds have pharmaceutical properties and in particular are useful in the treatment of immediate hypersensitivity conditions such as asthma.
