Abstract
Abstract LINEAR, HIGH MOLECULAR WEIGHT POLY(DIHALOGENALKENAMERS) ARE DISCLOSED. THE POLYMERS SHOW THE REPEATING UNIT -CHX-CHX(-CHR)N- IN WHICH X IS CHLORINE OR BROMINE, R IS HYDROGEN, METHYL OR PHENYL, AND N IS A WHOLE NUMBER FROM 3 TO 10. SOME OF THE POLYMERS ARE AMORPHOUS. OTHER OF THE POLYMERS, THOSE PREPARED FROM STEREOREGULAR POLYALKENAMERS BY THE PRESENT PROCESS, APPEAR TO BE CRYSTALLINE WHEN SUBJECTED TO X-RAY EXAMINATION. ALL OF THESE POLYMERS ARE VULCANIZABLE. THE NEW POLYMERS ARE PREPARED BY REACTING A POLYALKENAMER, THE REPEATING UNIT OF WHICH IS ESSENTIALLY -CH=CH-(-CHR)N- IN WHICH R AND N HAVE THE SIGNIFICANCE MENTIONED ABOVE, IN SOLUTION, WITH CHLORINE OR BROMINE UNTIL THE DOULBE BONDS PRESENT IN THE STARTING POLYALKENAMER TOTALLY DISAPPEAR.
