    CPC classification number: C08F20/34

    Abstract: Polymerisable anthranilic acid esters are obtained by heating acrylic or methacrylic acid esters containing hydroxyl groups with isatoic anhydride in an organic inert medium at temperatures of from 30* to 150*C in the presence of strong basis. They may be polymerised alone or in combination with other monomers by the methods of bulk solution suspension or emulsion polymerisation. Cross-linkage is possible even with the aid of polyisocyanates, formaldehyde and formaldehyde resins.

    Abstract: NOVEL AROMATIC DIAMINES HAVING THE GENERAL FORMULA

    ((2-NH2-PHENYL)-CO-X-)N-R

    WHEREIN N IS AN INTEGER OF FROM 2 TO 8, X IS SULFOR OR OXYGEN, AND R IS AN N-VALENT HYDROCARBON RADICAL WHICH MAY BE INTERRUPTED BY O OR S ATOMS AND WHICH IS OBTAINED BY REMOVING OH OR SH GROUPS FROM A POLYOL OR POLYTHIOL HAVING A MOLECULAR WEIGHT OF LESS THAN 600, P ARE PREPARED BY REACTING A COMPOUND HAVING THE FORMULA (HX)NR WHERE X, N AND R ARE AS DEFINED ABOVE WITH ABOUT N-EQUIVALENTS OF AN ISATOIC ACID ANHYDRIDE IN THE PRESENCE OF A STRONG BASE. THE AROMATIC DIAMINES OF THE INVENTION ARE PARTICULARLY USEFUL AS THE ACTIVE HYDROGEN CONTAINING COMPONENT FOR REACTION WITH POLYISOCYANATES IN THE PREPARATION OF SYNTHETIC RESINS BY THE ISOCYANATE-POLYADDITION PROCESS.

    CPC classification number: C08J9/108

    Abstract: THE INVENTION RELATES TO THE USE OF BISBENZAZIMIDE COMPOUNDS AS BLOWING AGENTS FOR THE PRODUCTION OF CELLULAR AND POROUS ARTICLES FROM ACRYLONITRILE, BUTADIENE AND STYRENE COPOLYMERS. THE BLOWING AGENTS DO NOT LIBERATE ANY CORROSIVE, DISCOLORING, MALODOROUS OR TOXIC DECOMPOSITION PRODUCTS.

    Abstract: 1. A PROCESS FOR THE PRODUCTION OF A NITRODIPHENYL AMINE OF THE FORMULA

    X-((O2N-)-PHENYLENE)-N(-Y)-(PHENYLENE)-X

    WHEREIN EACH X, WHICH MAY BE THE SAME OR DIFFERENT, IS HYDROGEN, ALKYL OR CYCLOALKYL HAVING UP TO 6 CARBON ATOMS, HALOGEN OR NITRO AND Y IS HYDROGEN OR ALKYL OR CYCLOALKYL HAVING UP TO 6 CARBON ATOMS, WHEREIN A URETHANE OF THE FORMULA

    X-((O2N-)-PHENYLENE)-OOC-N(-X)-(PHENYLENE)-X

    WHEREIN X AND Y ARE AS AFORESAID, IS DECARBOXYLATED BY HEATING IN THE PRESENCE OF A CATALYTIC AMOUNT OF A STRONG BASE SELECTED FROM THE GROUP CONSISTING OF ALKALI METAL SALTS OR ORGANIC ACIDS, ALKALI METAL CARBONATES, ALKALI METAL OXIDES AND ALKALI METAL HYDROXIDES AT A TEMPERATURE OF 110 TO 250*C.

    Abstract: COMPOUNDS HAVING TERMINAL AMINO GROUPS AND THE GENERAL FORMULA

    ((2-NH2-PHENYL)-CO-X-)N-R

    WHEREIN N IS AN INTEGER OF FROM 2 TO 8, X IS OXYGEN OR SULPHUR, AND R IS AN N-VALENT RADICAL OBTAINED BY THE REMOVAL OF HYDROXYL GROUPS OR MERCAPTO GROUPS FROM AN N-VALENT POLYALKYLENE ETHER POLYOL OF MOLECULAR WEIGHT 600 TO 10,000 OR FROM AN N-VALENT ALKYLENE THIOETHER POLYTHIOL OF MOLECULAR WEIGHT 600 TO 10,000. THESE COMPOUNDS ARE PREPARED BY REACTION POLYOLS WITH ISATOIC ACID, ANHYDRIDE AND ARE USEFUL IN REACTION WITH ORGANIC POLYISOCYANATES TO PREPARE ALL TYPE OF POLYURETHANE POLYMERS.
