Abstract: A dehydroabietic acid polymer including a skeleton represented by following formula (A) as a repeating unit: wherein, in formula (A), L represents a divalent organic group.

Abstract: Triglycerides and cholesterol in the bloodstream are important factors in the development of cardiovascular disease. The present invention discloses a nutritional supplement comprising a sterol and an omega-3 fatty acid, or an ester thereof, for lowering cholesterol and triglyceride levels in the bloodstream of a subject. Preferably, the sterol and omega-3 fatty acid are together in the form of an ester.

Abstract: The present invention relates to a method of catalyzing etherification, esterification, hydration, ether cleavage, isomerization alkylation, or other reactions which are catalyzable with an acid or molecular sieve catalyst. Said reactions are conducted using a novel, dual functional catalyst prepared with active components and a small amount of binder, wherein said dual functional catalyst comprises cylindrical pellets which are molded such that a cross-section or each pellet has a window lattice shape with external teeth, or a star shape with inner spokes.

Abstract: The compounds of Formula I are useful as immunosuppressive agents.

Abstract: Stable .alpha.-substituted boronic esters, e.g. for use in peptide synthesis, are prepared by reacting a substituted alkene of the formula: ##STR1## with a disubstituted borane of the formula: ##STR2## wherein: (i) R.sup.1 and R.sup.2 are each selected from various groups which are preferably not leaving groups;(ii) X is halogen or other leaving group;(iii) Y is H or lower alkyl;(iv) Q.sup.1 and Q.sup.2 are each selected from various groups which are preferably such that the borane is non-hydrolyzable, and particularly Q.sup.1 and Q.sup.2 together may represent a residue of a diol such as catechol or pinanediol.

Abstract: D(+)-threo-2-hydroxy-3-(2-aminophenylthio)-3-(4-methoxyphenyl)propionic acid, an important intermediate in the synthesis of diltiazem hydrochloride, is obtained in better yields and high optical purity by a novel resolution process comprising the reaction of 2 moles of the (.+-.) racemic acid with 1 mole of quinine and 1 mole of a base in a suitable polar solvent system to form a salt of the D(+) acid and quinine which precipitates; separating said salt and decomposing it with a strong base.

Abstract: Disclosed are 2,4,6-trialkyl-3-hydroxybenzyl esters of monocarboxylic resin acids and olefin polymer compositions stabilized therewith.

Abstract: Toner particles comprising a polyester binder and a charge control agent are provided wherein such agent is a quaternary ammonium salt having one or more ester-containing moieties. Such an ester-containing salt causes toner particles to display lower fusing temperature, improved paper adhesion indexes, and improved polyester binder compatibility compared to nonesterified salts.

Abstract: The present invention relates to a process for the separation of the enantiomers of threo-2-hydroxy-3-(2'- aminophenylthio)-3-(4"-methoxyphenyl)-propionic acid, which is an important intermediate in the synthesis of pharmacologically active compounds, by means of the direct crystallization of the relevant cyclohexylaminic salt.According to a preferred form of practical embodiment of the present invention, the optically pure acid is recovered as the hydrochloride of the corresponding methyl ester.

Abstract: Toner particles comprising a polyester binder and a charge control agent are provided wherein such agent is a quaternary ammonium salt having one or more ester-containing moieties. Such an ester-containing salt causes toner particles to display lower fusing temperature, improved paper adhesion indexes, and improved polyester binder compatibility compared to nonesterified salts.

Abstract: The disodium ethoxylated rosin half esters of sulfosuccinic acid prepared from the 1-5 mole rosin ethoxylates are disclosed as foam stabilizers for a variety of latices as well as latex compositions containing same which are processable into a non-gelling, heat-curable solid foam suitable for use as foam carpet backing and the method of preparing the latex compositions.
