Abstract: Photosensitive homopolymers and substantially non-crosslinked copolymers containing the recurring unit: ##EQU1## R.sub.1 may be substituted or unsubstituted alkylene, aralkylene, alkoxyalkylene or aryloxyalkylene. R.sub.2 is a substituted or unsubstituted aryl group or heterocyclic group having aromatic character. R.sub.3, R.sub.4, and R.sub.5 are hydrogen, halogen or lower alkyl. R.sub.6 and R.sub.7 may be hydrogen, halogen, nitro, lower alkyl, phenyl, substituted phenyl, phenoxy and lower alkoxy. Lithographic plates bearing these photosensitive polymers can be stored without deterioration for extended periods prior to exposure, and produce highly abrasion resistant plates on being exposed. The photosensitive polymers of the invention are preferably produced by homopolymerization of novel monomers having the general formula ##EQU2## where R.sub.1 .sub.' is alkylene, haloalkylene, alkoxyalkylene, aminoalkylene, cycloalkylene, aralkylene, cycloalkylalkylene, cyanoalkylene, and aryloxyalkylene, and R.sub.2, R.

Abstract: m-Phenylene-N,N-methyl-(m-chlorophenyl)-Dicarbamate is synthesized by reaction of resorcinol with methylisocyanate and m-chlorophenylisocyanate. Product is useful for pre-emergence herbicide in agricultural formulation.

Abstract: Treatment of DL-phenylalanine alkyl esters with N-acyl-D-phenylalanines results in the formation of insoluble salts of the L-phenylalanine alkyl esters and N-acyl-D-phenylalanines. The salts are isolated and decomposed to afford the desired L-phenylalanine alkyl esters, which are important starting materials in the preparation of artificial sweetening agents.

Abstract: Novel aromatic carboxylic amides of the general formula: ##EQU1## wherein each of R.sub.1 and R.sub.2 is a hydrogen atom or an alkyl group having 1-4 carbon atoms, R.sub.3 and R.sub.4 are hydrogen atoms or together form another chemical bond, each X is a hydroxyl group, a halogen atom, an alkyl group having 1-4 carbon atoms and an alkoxy group containing 1-4 carbon atoms, and n is an integer of 1-3, with the proviso that when two Xs are alkyl or alkoxy groups, they may be connected together to form a ring, as well as pharmaceutically acceptable salts thereof.These compounds possess a strong antiallergenic action and are thus useful for treatment of asthma, hay fever, anticaria and atopic dermatitis.The above aromatic carboxylic amides can be prepared by reacting a reactive functional derivative of the general formula: ##EQU2## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.

Abstract: This invention relates to triiodized dicarboxylic acid anilides containing radioactive iodine of the formula ##SPC1##WhereinR.sub.1 is hydrogen, carboxyl, N-acylamino, N-acylaminomethyl, N-alkyl-N-acylamino, N-butyrolactamyl, or an ##EQU1## group, wherein R.sub.3 and R.sub.4 are each hydrogen, lower alkyl or hydroxyalkyl, or R.sub.3 and R.sub.4 together with the nitrogen atom form a 5 to 7 member heterocyclic ring which can contain a further oxygen, nitrogen or sulfur hetero atom;R.sub.2 is hydrogen, lower alkyl or hydroxyalkyl; andX is straight-chain or branched alkylene of 1-14 carbon atoms, which can be interrupted by one or more oxygen or sulfur atoms,As well as the physiologically acceptable salts thereof with suitable bases. These compounds are especially useful in the preparation of radioactive functional diagnostic agents.

Abstract: The present invention relates to amine, alkali metal and alkaline earth metal salts of N-benzene sulfonyl carbamic acid esters and to lower alkenyl N-benzene sulfonyl carbamates. These compounds are useful as herbicides.

Abstract: 3-Amino-4-anilino-5-sulfamoylbenzoic acids, e.g. those of the formula ##SPC1##R = an aliphatic or araliphatic radicalR' = h, alkyl, or aminophenylAlkyl esters or salts thereof are diuretic agents.

Abstract: Improved curing agents having long pot life for use with urethane elastomers are prepared by reacting orthochloroaniline, an ester of anthranilic acid, and formaldehyde in selected molar ratios in an acid medium.

Abstract: Method of preparing 5-halo-2,3-phenylenediamine-1-carboxylic acids having the following formula: ##SPC1##Wherein X is Cl, Br or F by reacting a 2,5-dihalo-3-nitrobenzoic acid with ammonium hydroxide to yield 5-halo-3-nitro anthranilic acid followed by a reduction of the resultant product. The 5-halo-2,3-phenylenediamine-1-carboxylic acids are useful as herbicides and as intermediates for use in the preparation of dyestuffs, photographic developers, pharmaceuticals, antioxidants and the like.

Abstract: A two-stage process for producing para-aminobenzoic acid by first reacting certain lower alkyl or glycol monoesters of terephthalic acid or specific salts thereof or mixtures thereof with ammonia in liquid phase at elevated temperatures and pressures to obtain a terephthalic acid monoamide intermediate, removing substantially all ammonia from this intermediate and then converting it into the para-aminobenzoic acid product by the Hofmann reaction, preferably using a sodium hypochlorite solution. The para-aminobenzoic acid, either as the free acid or in the form of its salts or esters is a known product having many uses.

Abstract: The invention disclosed is for a new and novel class of liquid polyene compositions formed of a molecule containing at least two unsaturated carbon-to-carbon bonds disposed at terminal positions on a main chain backbone of the molecule. The molecule includes unsaturated carbon-to-carbon bonds connected by a divalent chemically compatible derivative to a stable, organic, polyvalent, and polymeric member free of reactive carbon-to-carbon unsaturation and free of highly water-sensitive members. The new class of liquid polyene compositions which have a molecular weight in the range 300 to 20,000, and a viscosity in the range from essentially 0 to 20 million centipoises at 70.degree.C., may usefully form a component of a system which upon curing in the presence of a free radical generator and a polythiol, forms odorless, solid, elastomeric products. The cured products may be used as sealants, coatings, adhesives and molded articles.
