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.

Abstract: THERE ARE DISCLOSED NEW HIGH MOLECULAR WEIGHT COPOLYALKENAMERS THE CHAINS OF WHICH ARE MADE UP OF TWO OR MORE MORE ALTERNATING TYPES OF MONOMERIC UNITS ARRANGED ACCORDING TO EITHER HOMO-SEQUENCES OR BOTH HOMO-SEQUENCES AND HETERO-SEQUENCES (WHICH IS TO SAY SEQUENCES MADE UP OF STATISTICALLY DISTRIBUTED MONOMERIC UNITS). ALSO DISCLOSED IS A METHOD OF PREPARING THE NEW COPOLYALKENAMERS BY REACTING A HOMOPOLYALKENAMER, PREFERABLY DISSOLVED IN A SUITABLE SOLVENT, WITH ONE OR MORE CYCLCOLEFINS (OTHER THAN THE ONE MAKING UP THE STARTING HOMOPOLYALKENAMIMER) IN CONTACT WITH A PARTICULAR CATALYTIC SYSTEM PREPARED FROM A TRANSITION METAL SALT SUCH AS A TUNGSTEN SALT; PREFERABLY BUT NOT NECESSARILY AN OXYGENATED COMPOUND SUCH AS MOLECULAR OXYGEN; AND A DERIVATIVE OF A METAL BELONGING TO GROUPS I, II, III OR IV OF THE MENDELYEEV PERIODIC TABLE, SUCH AS, FOR INSTANCE, A HYDRIDE OR ORGANOMETALLIC COMPOUND OF ALUMINUM.

Abstract: NEW PRODUCTS ARE DISCLOSED WHICH ARE SUBSTITUTED (CO) POLYALKAMERS OF HIGH MOLECULAR WEIGHT AND THE MACROMOLECULES OF WHICH CONSIST ESSENTIALLY OF THE SAME OR DIFFERENT REPEATING UNITS AND ARE CHARACTERIZED IN EXHIBITING A MAIN LINEAR SATURATED HYDROCARBON CHAIN HAVING TWO SIDE SUBSTIUENTS LINKED TO ADJACENT CARBON ATOMS. ONE OF THE SUBSTITUENTS IS A CHLORINE ATOM; THE OTHER IS AN ESTER GROUP. THE NEW SUBSTITUTED (CO) POLYALKAMERS ARE PREPARED BY REACTING A POLYALKENAMER MADE UP OF THE SAME OR DIFFERENT UNITS, DISSOLVED IN METHYLENE CHLORIDE, ALONE OR MIXED WITH METHANOL OR BENZENE, WITH (A) AN ORGANIC MONOBASIC ACID CONTAINING FROM 1 TO 18 CARBON ATOMS AND HAVING A DISSOCATION CONSTANT IN WATER AT 25*C. OF AT LEAST 1.65X**-5, AND (B) AN ALKYL HYPOCHLORITE. THE SUBSTITUTED CO (POLYALKAMERS) OF THIS INVENTION HAVE THE FOLLOWING FORMULA:

-CH(-CL)-CH(-O-R)-(CH(-R''))Z-

IN WHICH R IS A RADICAL CONTAINING FROM 1 TO 18 CARBON ATOMS OF AN ORGANIC MONOBASIC ACID HAVING A DISSOCIATION CONSTANT IN WATER AT 25*C. OF AT LEAST 1.65X10**-5; THE R'' GROUPS ARE HYDROGEN ATOMS OR A PART OF THEM ARE METHYL GROUPS; Z IS A WHOLE NUMBER FROM 3 TO 10; AND THE RATIO BETWEEN THE METHYLENE GROUPS AND THE SUM OF THE CHC1 AND CHOR GROUPS IS COMPRISED BETWEEN 1.5:1 AND 5:1.
