Abstract: A curable coating composition for paints and printing inks, which contains an acrylic or methacrylic acid ester prepared by addition reacting a monocyclic phenolic compound such as resorcine with ethylene or propylene oxide to produce an adduct and then esterifying the thus-produced adduct with acrylic or methacrylic acid to prepare the acrylic or methacrylic acid ester.

Abstract: Bicyclic compounds useful in the prophylaxis and treatment of allergic diseases, pharmaceutical compositions containing the same, methods of administration of the compositions, intermediates useful in preparing the compounds and conversion of the intermediates to the bicyclic compounds. Examples of compounds are substituted coumarins and indanediones and their pharmaceutically acceptable salts.

Abstract: High purity monomers, such as methyl p-hydroxymethylbenzoate, are produced by selective reduction of dicaboxylic acid monoesters with diborane. The resultant monomers are suitable for producing new polymers with improved physical properties.

Abstract: Esters of acetylsalicylic acid with polyols of the formula:HO -- A -- S -- (CH.sub.2).sub.n -- S -- A -- OH (I)in which n is an integer of from 5 to 15 and each A group represents a C.sub.2 -C.sub.6 linear or branched hydrocarbyl group which can contain an --OH group are particularly useful as hypolipidaemic, hypocholesterolaemic, anti-blood clotting and anti-atherosclerosis agents.

Abstract: Novel liquid crystal materials are provided having the general formula ##STR1## where A is a 4-alkylphenyl group and B is a 2-(6-alkyl)naphthyl group, or vice versa, wherein the alkyl groups in A and B may be the same or different. These materials have a dielectric anisotropy sign change at moderate frequencies, i.e., in the range 1kHz to 50kHz and are thus useful for twisted nematic device cells of the frequency switching type.

Abstract: Novel liquid crystal materials which are trans-4-alkylcyclohexane-1-carboxylic acid esters are provided having the general formula: ##STR1## where R is a normal or branched chain alkyl group, which may also contain a chiral center, containing up to ten carbon atoms and X is selected from the groups: ##STR2## where A is a cyano group, a normal or branched chain alkyl group, which may also contain a chiral center, containing up to ten carbon atoms or an alkoxy group in which the alkyl group is as defined immediately above, and where Y is a halogen, preferably chlorine, or hydrogen.
