Abstract 1. A PROCESS FOR PREPARING A CARBONACEOUS FIBER FROM A VINYLIDENE CHLORIDE POLYMER FILAMENT COMPRISING THE SEQUENTIAL STEPS OF: (1) TREATING SAID VINYLIDENE CHLORIDE POLYMER FILAMENT WITH AN ORGANIC AMINE HAVING THE FORMULA R-NH2 WHEREIN R IS ALKYL CONTAINING FROM 1 TO 4 CARBON ATOMS AT A TEMPERATURE LESS THAN ABOUT 125*C. IN THE ESSENTIAL ABSENCE OF MOISTURE UNTIL SAID FILAMENT IS FROM ABOUT 25 TO 80 PERCENT DEHYDROHALOGENATED BYT WUTHO OUT SIGNIFICANT LOSS IN FILAMENT STRUCTURAL INTEGRITY, AND (2) CARBONIZING SAID FILAMENT BY SUBJECTING THE SAME TO A TEMPERATURE WHICH IS INCREASED FROM AN INITIAL VALUE OF AT LEAST ABOUT 90*C. TO A FINAL VALUE OF UP TO ABOUT 1500*C. OVER A PERIOD OF AT LEAST 5 MINUTES.
