Abstract: THE OBJECTS OF THE INVENTION ARE SEGMENTED POLYURETHANE ELASTOMERS, PREFERABLY ELASTOMERIC FIBERS, FOILS AND SOLUTIONS THEREOF, BEING PREPARED BY REACITING AN NCOPOLYMER WITH A SEMICARTBAZIDE-ALKYL-AMINE OR -ARYLAMINE AS CHAIN EXTEDNDING AGENTS-UP TO 45 MOL PERCENT OF THE TOTAL AMOUNT OF CHAIN EXTENDERS-CAN BE USED. THE REACTION IS EFFECTED IN HIGHLY POLAR SOLVENTS. THE OBTAINED ELASTOMERS HAVE IMPROVED PROPERTIES, ESPECIALLY IMPROVED HEAT DISTORTION TEMPERATURE AND IMPROVED HYDROTHERMAL PROPERTIES. A FURTHER OBJECT OF THE INVENTION ARE NEW SEMICARBAZIDE AMINO COMPOUNDS.
