Abstract: THE INVENTION RELATES TO ANTHRANILIC ACID ESTERS WHICH ARE ALKYLATED IN THE NUCLEUS REPRESENTED BY THE GENERAL FORMULA

2-(RO-CO-),3-(H2N-),((4-R1,R2,R3-PHENYL)-Z-)-ANTHRACENE

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

Abstract: NOVEL HIGH MOLECULAR WEIGHT POLYESTERAMIDES WITH OUTSTANDING THERMAL STABILITY AND MECHANICAL STRENGTHS ARE OBTAINED BY POLYCONDENSING AN AROMATIC DICARBOXYLIC ACID DIHALIDE SIMULTANEOUSLY WITH FROM 90 TO 10 MOL PER CENT OF AN AROMATIC OR ALIPHATIC DIHYDROXY COMPOUND AND FROM 10 TO 90 MOL PERCENT OF AN AROMATIC OR ARALIPHATIC DIAMINO COMPOUND. THE POLYCONDENSATION PRODCUTS CAN CONTAIN CHLORINE OR BROMINE AND ETHER, SULPHIDE OR SULPHONE GROUPS. THE RATIO OF ESTER AND AMIDE GROUPS IN THE POLYCONDENSATED CAN BE VARIED IN LIMITS BETWEEN ABOUT 1:9 AND 9:1.
