Ultrastable polymers of bbb type,articles such as fibers made therefrom,and high temperature process for forming such polymers and articles |
| abstract |
PLASTIC ARTICLES OF PARTICULARLY HIGH THERMAL STABILITY, SUCH AS FIBERS OR OTHER EXTRUDED SHAPES, ARE MADE FROM "BBB" TYPE POLYMERS, I.E., POLYMERS OF THE POLYAROYLENEBENZIMIDAZOLE TYPE, OR MORE PARTICULARLY OF THE POLYBISBENZIMIDAZOBENZOPHENANTHROLINE TYPE, BY HEAT TREATMENT OF SUFFICIENTLY ORIENTED POLYMER AT A ULTRA-HIGH TEMPERATURE BETWEEN ABOUT 750* AND 1500*C. FOLLOWING PREHEATING AT AN INTERMEDIATE TEMPERATURE IN THE 500* TO 700* C. RANGE. AS A RESULT OF SUCH A HIGH-TEMPERATURE TREATMENT A NEW KIND OF POLYMER STRUCTURE IS OBTAINED WHICH IS ATTRIBUTED TO THE SPLITTING OUT OF THE CARBONYL GROUPS FROM THE BBB POLYMER MOLECULE. |
