摘要： A neutral elastomer is prepared by the urethane linking reaction of diisocyanates with tertiary amino diols. The neutral elastomer is quaternized and is then reacted with an anionic polymer such as heparin to form ionically bonded block elastomeric copolymers. The heparin copolymer has non-thrombogenic characteristics. It can be dissolved in solvents and ultized to form a non-clotting coat on the blood lines in kidney machines.

摘要： FILM- AND FIBER-FORMING SOLUTIONS OF HIGH-MOLECULARWEIGHT, LINEAR POLYHYDRAZIDES DISSOLVED IN N,N-DIMETHYL ACETAMIDE SOLVENT CONTAINING DISSOLVED INORGANIC HALIDE ARE PROVIDED. THE POLYHYDRAZIDES CONTAIN RECURRING STRUCTURAL UNITS:

-NH-NH-CO-(1,4-PHENYLENE)-CO-NH-NH-CO-(1,4-PHENYLENE)-CO-,

AND -NH-NH-CO-CO-NH-NH-CO-(1,4-PHENYLENE)-CO-

IN A RATIO BETWEEN 1:9 AND 9:1 AND ARE PREPARED IN DIMETHYL ACETAMIDE CONTAINING DISSOLVED, E.G., LITHIUM CHLORIDE BY POLYMERIZING THEREIN APPROPRIATE AMOUNTS OF REACTANTS WHICH INCLUDE TEREPHTHALOYL CHLORIDE, TEREPHTHALIC DIHYDRAZIDE AND OXALIC DIHYDRAZIDE. THE RESULTING SOLUTIONS MAY BE EXTRUDED INTO FIBERS OR CAST INTO FILMS BY CONVENTIONAL SOLUTION SPINNING AND CASTING. FIBERS PRODUCED FROM THESE SOLUTIONS HAVE VERY HIGH VALUES OF TENSILE STRENGTH AND MODULUS, AND ARE PARTICULARLY USEFUL IN REINFORCING RUBBER AND PLASTIC ARTICLES.

摘要： AROMATIC AMIDE-HYDRAZIDE COPOLYMERS ARE PROVIDED. THESE COPOLYMERS ARE CHARACTERIZED AS BEING FIBER-FORMING AND HAVING RECURRING STRUCTURAL UNITS OF

(-(NH-NH-CO-Z-CO-NH-NH-CO-Y-CO)P-(NH-X-NH-CO-Y-CO)Q-)

X AND Y ARE DIVALENT AROMATIC RADICALS; AND Z IS A DIVALENT AROMATIC RADICAL OR A CHEMICAL BOND. P AND Q ARE INTEGERS. THE AROMATIC RADICALS HAVE A MOLECULAR WEIGHT OF LESS THAN 250 AND ARE COMPRISED OF ONE OR TWO METAOR PARA-PHENYLENE LINKAGES. THE RATIO OF P:Q IS IN THE RANGE OF FROM 1:3 THROUGH 9:1. SOLUTIONS OF THESE POLYMERS IN AMIDE SOLVENTS ARE SUITABLE FOR USE IN SPINNING FILAMENTS, EVEN THOUGH GREATER THAN 65% OF THE ARYLENE MOIETIES ARE PARA-PHENYLENE.
