    摘要： ALTERNATE COPOLYMERS OF ACRYLONITRILE AND BUTADIENE ARE MANUFACTURED BY MEANS OF PHOTOPOLYMERIZATION IN THE PRESENCE OF (A) A CATALYST COMPRISING AT LEAST ONE COMPOUND SELECTED FROM THE GROUP CONSISTING OF CERTAIN METAL HALIDES AND ORGANIC METAL HALIDES AND ORGANOMETALLIC COMPOUNDS AND (B) A PHOTOSENSITIZER COMPRISING AT LEAST ONE COMPOUND SELECTED FROM THE GROUP CONSISTING OF BENZENE AROMATIC HAYDROCARBONS AND HALIDES SOME POLYNUCLEAR AROMATIC HYDROCARBONS AND HALIDES THEREOF, SOME HETEROCYCLIC COMPOUNDS, AROMATIC OR ALIPHATIC HYDROCARBON COMPOUNDS, SOME KETONE, GLYOXAL AND ALDEHYDE COMPOUNDS, SOME SULFONIC COMPOUNDS. THEREBY THE ALTERNATING COPOLYMERS CAN BE OBTAINE IN HIGHER YIELD AND WITH LESSER GEL FORMATION. AS OCCASION DEMANDS (C) AN ANTI-GELLING AGENT IS ADDED TO THE REACTANTS WHICH AGENT COMPRISES AT LAST ONE COMPOUND SELECTED FROM A GROUP CONSISTING OF ALIPHATIC HALIGENATED HYDROCARBONS ALICYCLIC HALOGENATED HYDROCARBONS, IODINE, SULFIDE, OR DISULFIDE HYDROCARBONS, THIOL, OR DITHIOL HYDROCARBONS, AROMATIC ETHYLENIC HYDROCARBONS, SOME TRANSITION METAL COMPOUNDS.

    摘要： BUTADIENE-ISOPRENE COPOLYMER HAVING A BUTADIENE UNIT OF AT LEAST 90% OF CIS-1,4 STRUCTURE AND AN ISOPRENE UNIT OF AT LEAST 95% OF 1,4-STRUCTURE IS PRODUCED BY COPOLYMERIZING BUTADIENE AND ISOPRENE BY MEANS OF THREE COMPONENT CATALYST CONSISTING OF (A) A COMPOUND SELECTED FROM THE GROUP CONSISTING OF AN ORGANIC CARBOXYLIC ACID SALT AND AN ORGANIC COMPLEX COMPOUND OF NICKEL, (B) A COMPOUND SELECTED FROM THE GROUP CONSISTING OF BORON TRIFLUORIDE AND ITS COMPLEX COMPOUND WITH AN OXYGENCONTAINING ORGANIC COMPOUND AND (C) AN ORGANOMETALLIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF TRIALKYLALUMINUM, DIALKYLZINC, ALKYLLITHIUM AND DIALKYLALKOXYALUMINUM, BUTADIENE/ISOPRENE FEED RATIO BEING IN THE RANGE OF 90/10-70/30 (MOLE RATIO), THE MOLE RATIO OF SAID (C)-COMPONENT TO SAID (A)-COMPONENT BEING AT LEAST 0.5 AND THE MOLE RATIO OF SAID (C)-COMPONENT TO SAID (B)-COMPONENT BEING WITHIN THE RANGE OF 0.5 TO 2.0.

    摘要： THERE IS DISCLOSED A PROCESS FOR POLYMERIZING ISOPRENE, IN HOMOGENEOUS PHASE, TO HIGH POLYMERS IN WHICH THE PROPORTION OF ISOPRENE UNITS HAVING CIS-1,4 ENCHAINMENT IS PRACTICALLY IDENTICAL WITH THAT OF NATURAL RUBBER. THE PROCESS UTILIZES A TERNARY CATALYST SYSTEM PREPARED BY MIXING TICL4, AN ORGANOMETALLIC COMPOUND OF THE TYPE ALR2CL IN WHICH R IS AN ALKYL GROUP, AND AN UNSATURATED POLYMER, PREFERABLY A POLYBUTADIENE OR POLYISOPRENE HAVING AT LEAST PREVALILINGLY CIS-1,4 STRUCTURE AND A MOLECULAR WEIGHT SUCH THAT THE CATALYST IS SOLUBLE IN THE POLYMERIZATION MIXTURE AND PREFERABLY CORRESPONDING TO AN INTRINSIC VISCOSITY OF FROM 0.4 TO 0.8 DL./G., DETERMINED IN TOLUENE AT 30*C.

    摘要： DISCLOSES THE USE OF INITATOR ACTIVATORS IN THE POLYMERIZATION OF AN ETHYLENICALLY UNSTURATED MONOMER CAPABLE OF BEING POLYMERIZED BY HYDROGEN PEROXIDE AND ORGANIC HYROPEROXIDE CATALYSTS IN A MUTUAL SOLVENT POLYMERIZATION SYSTEM, MUTUAL SOLVENTS BEING LOWER ALCOHOLS, ACETONE, METHYL ETHYL KETONE, DIOXANE AND TETRAHYDROFURAN, THE INIATOR ACTIVATORS BEING SOLUBEL IN THE NON-AQUEOUS MUTUAL SOLVENT BY AT LEAST 2% AND BEING A CHLORIDE, BROMIDE, NITRATE, THIOCYANATE OR SULFATE SALT OF MAGNESIUM, LITHIUM, CALCIUM, ZINC, POTASSIUM, STRONTIUM, AMMONIA, QUATERNARY AMMONIA, AND HYDROCHLORIC AND HYDROBROMIC ACID SALTS OF PRIMARY, SECONDARY AND TERTIARY AMINES.
