摘要： ALTERNATING COPOLYMERS OF A CONJUGATED DIENE WITH A CONJUGATED POLAR ETHYLENICALLY UNSAURATED MONOMER, WHEREIN THE CONJUGATED DIENE UNIT AND THE CONJUGATED POLAR ETHYLENICALLY UNSATURATED MONOMER UNIT ARE BONDED SUBSTTANTIALLY ALTERNATELY, ARE PRODUCED BY COPOLYMERIZING SAID CONJUGATED DIENE WITH SAID CONJUGATED POLAR ETHYLENICALLY UNSAURATED MONOMER BY MEANS OF A CATALYST PREPARED FROM A COMPONENT (A) OF A COMPOUND OF A TRANSITION METAL OF THE GROUP IV OR V IN THE PERIODIC TABLE, PROVIDED THAT THE CHELATE COMPOUNDS ARE EXCEPTED, AND A COMPONENT (B) OF ZINC HALIDE OR AN ALUMINUM COMPOUND CONTAINING HALOGEN. THIS COPOLYMERIZATION ACTIVITY CAN BE IMPROVED BY ADDING A COMPONENT (C) OF A RADICAL INITIATOR SELECTED FROM THE GROUP CONSISTING OF ORGANIC PEROXIDES, AZONITRILE COMPOUNDS AND TRIALKYLBORON-OXYGEN SYSTEM TO THE AOVE DESCRIBED COMPONENTS (A) AND (B). FURTHERMORE, THE MOLECULAR WEIGHT OF THE ALTERNATING CO POLYMER CAN BE ADJUSTED BY ADDING A MOLECULAR WEIGHT REGULATOR SELECTED FROM THE GROUP CONSISTING OF MERCAPTANS AND CARBON POLYHALIDES CONTAINING BROMINE OR IODINE AS AN ESSENTIAL COMPONENT TO THE POLYMERIZATION REACTION SYSTEM.

摘要： ALTERNATING COPOLYMERS OF A CONJUGATED DIENE WITH A CONJUGATED POLAR VINYL MONOMER, WHEREIN THE CONJUGATED DIENE UNIT AND THE CONJUGATED POLAR VINYL MONOMER UNIT ARE BONDED SUBSTANTIALLY ALTERNATELY, ARE PRODUCED BY COPOLYMERIZING SAID CONJUGATED DIENE WITH SAID CONJUGATED POLAR VINYL MONOMER BY MEANS OF A CATALYST PREPARED IN THE PRESENCE OF A CONJUGATED POLAR VINYL MONOMER TO BE USED IN THE COPOLYMERIZATION REACTION FROM A COMPONENT (A) OF A COMPOUND OF A TRANSITION METAL OF THE GROUP IV OR V IN THE PERIODIC TABLE AND A COMPONENT (B) SELECTED FROM THE GROUP CONSISTING OF AN ALUMINUMCONTAINING COMPOUND; A COMBINATION OF AN ALUMINUM COMPOUND AND A TIN COMPOUND; A COMBINATION OF AN ORGANOMETALLIC COMPOUND AND A METAL HALIDE; AND AN ORGANOALUMINUM COMPOUND. THIS COPOLYMERIZATION ACTIVITY CAN BE IMPROVED BY ADDING A COMPONENT (C) OF A RADICAL INITIATOR SELECTED FROM THE GROUP CONSISTING OF ORGANIC PEROXIDES, ORGANONITRILE COMPOUNDS AND TRIALKYLBORON$ OXYGEN SYSTEMS TO THE ABOVE DESCRIBED COMPONENTS (A) AND (B). FURTHERMORE, THE MOLECULAR WEIGHT OF THE ALTERNATING COPOLYMERS CAN BE CONTROLLED BY ADDING A MOLECULAR WEIGHT REGULATOR SELECTED FROM THE GROUP CONSISTING OF MERCAPTANS, DISULFIDES AND CARBON POLYHALIDES CONTAINING BROMINE OR IODINE AS AN ESSENTIALLY COMPONENT TO THE POLYMERIZATION REACTION SYSTEM.

摘要： A INVENTION LIES IN A PROCESS FOR MANUFACTURING AN ALTERNATING COPOLYMER OF BUTADIENE AND ACRYLONITRILE IN SUSPENSION PHASE UNDER THE FOLLOWING CONDITIONS IN COMBINATION. IN THE FIRST PLACE, THE CATALYST SYSTEM COMPRISES IN COMBINATION (A) (1) AT LEAST ONE OF ORGANOALUMINUM HALIDES OR (2) AT LEAST TWO OF ALUMINUM AND ZINC COMPOUNDS IN COMBINATION, AND (B) A VANADIUM COMPOUND SOLUBLE IN A HYDDROCARBON. SECONDLY THE SUSPENSION MEDIUM IS ANY ONE SELECTED FROM THE GROUP CONSISTING OF (I) SATURATED ALIPHATIC HYDROCARBONS, (II) SATURATED ALICYCLIC HYDROCARBONS, (III) SATURATED HYDROCARBON HALIDES AND (IV) AROMATIC HYDROCARBONS EACH OF WHICH HAS A BOILING POINT LOWER THAN 150*C. THE ACCUMULATIVE TOTAL OF THE PRODUCTS OF THE SQUARE ROOT OF THE COHEERENT ENERGY DENSITY AND OF THE VOLUME FRACTION WITH RESPECT TO EACH OF THE MONOMERS AND THE MEDIUM MUST FALL IN THE RANGE OF 6 TO 9.1. FINALLY IT IS NECESSARY TO ADD A STABILIZER AS COMPRISING AT LEAST ONE SELECTED FROM THE GROUP CONSISTING OF ALIPHATIC AND ALICYCLIC ZINC CARBOXYLATES HAVING 8 TO 24 CARBON ATOMS AND AN INACTIVE INORGANIC POWDERY MATERIAL OF A DIMENSION SMALLER THAN 100U.
