    摘要： A NOVEL ALTERNATING COPOLYMER COMPOSED OF THE GROUP (B) MONOMER CONSISTING OF AT LEAST ONE A-,B-OR A,B-MULTISUBSTITUTED CONJUGATED VINYL COMPOUND, AND THE GROUP (A) MONOMER CONSISTING OF AT LEAST ONE MONOMER SELECTED FROM THE GROUP OF OLEFINS, HALOOLEFINS, INTERNAL OLEFINS, POLYENES, ACETYLENES, AND CARBONYL COMPOUNDS OR THIOCARBONYL COMPOUNDS; THE UNITS FROM THE GROUP (A) MONOMER ALWAYS ALTERNATING WITH THE UNITS FROM THE GROUP (B) MONOMER. SAID ALTERNATING COPOLYMER IS PRODUCED BY CONTACTING AT LEAST THE GROUP (B) MONOMER OF THE TWO GROUPS WITH AN ORGANOALUMINUM OR ORGANOBORON HALIDE TO FORM A COMPLEX AND THEN CONTACTING THE REMAINING MONOMER WITH THE COMPLEX FORMED. WHEN MONOMERS OF BOTH GROUPS (A) AND (B) ARE PROPERLY CHOSEN, SAID NOVEL ALTERNATING COPOLYMER CAN BE USEFUL AS A MATERIAL FOR THE PRODUCTION OF FILM, FIBER AND MOLDED ARTICLES, AND AS AN ADDITIVE FOR THE PLASTICS PROCESSING.

    摘要： AN ALTERNATING COPOLYMER COMPRISING UNSATURATED COMPOUNDS CONTAINING A SULFONIC ACID GROUP (MONOMER OF GROUP A) AND NON-SUBSTITUTED OR SUBSTITUTED CONJUGATED VINYL COMPOUNDS (MONOMER OF GROUP B) IS PREPARED FROM THE MONOMERS OF GROUP A SUCH AS VNYLSULFONIC ACIDS, ALLYLSULFONIC ACIDS, STYRENESULFONIC ACIDS, VINYLOXYSULFONIC ACIDS, AND ALLYLOXYSULFONIC ACIDS AND THE MONOMERS OF GROUP B SUCH AS ACRYLONITRILE, ACRYLIC ACID, THIOACRYLIC ACID, OR THEIR DERIVATIVES USING AN ORGANOMETALLIC HALIDE SUCH AS ORGANOALUMINUM HALIDE OR ORGANOBORON HALIDE OR MODIFIED CATALYST THEREOF. THE PRODUCE COPOLYMER IS USEFUL FOR SHAPING A FILM, FIBERS, OR OTHER MOLDING OR FOR MODIFYING THE MOLDINGS, OR USEFUL AS AN ION EXCHANGE RESIN OR A READILY DYEABLE POLYMER.

    摘要： THE SOLUTION POLYMERIZATION OF ACRYLONITRILE POLYMERS AND COPOLYMERS IS FACILITATED WHEN IT IS CONDUCTED UNDER AGITATION IN THE PRESENCE OF AN INERT DISPERSION MEDIUM. THE SOLVENT USED IS ONE THAT WILL DISSOLVE BOTH THE MONOMER AND THE RESULTING POLYMER. THE DISPERSION MEDIUM IS A LIQUID THAT IS NOT UNIFORMLY MISCIBLE WITH THE SOLVENT AND IT WILL NOT DISSOLVE EITHER THE MONOMER OR THE POLYMER. UPON PERMITTING THE REACTION PRODUCT, A DISPERSION, TO STAND QUIETLY IT SEPARATES INTO TWO LIQUID PHASES THAT CAN BE SEPARATED BY DECANTATION. THE PREFERRED DISPERSION MEDIA ARE LIQUID HYDROCARBONS HALOGENATED OR NOT, THAT HAVE A BOILING POINT ABOVE 268*C.

    摘要： COPOLYMERS OF AT LEAST 80% OF ACRYLONITRILE, ABOUT 0.1 TO 5% OF AN ETHYLENICALLY UNSATURATED ORGANIC SULFONIC ACID OR SALT THEREOF AND UP TO 19.9% OF AT LEAST ONE ETHYLENICALLY UNSTURATED MONOMER WHICH IS COPOLYMERIZABLE WITH ACRYLONITRILE AND THE AFORESAID SULFONIC ACID OR ITS SALT, ARE PREPARED IN AQUEOUS POLYMERIZATION MEDIUM IN THE PRESENCE OF AN ORGANIC COMPOUND WHICH IS A NON-SOLVENT FOR THE COPOLYMER BUT IS A SOLVENT FOR THE MONOMER(S) OTHER THAN THE SULFONIC ACID O ITS SALT.
