    摘要： A process for preparing an alternating copolymer of butadiene and acrylonitrile which comprises contacting butadiene and acrylonitrile in liquid phase with a catalyst, said catalyst comprises the first component selected from the group consisting of an aluminum halide and a zinc halide, a vanadium compound as the second component and the third component selected from the group consisting of an organo-aluminum compound, an organozinc compound and an organolithium compound. The alternating copolymers obtained by this invention are rubber-like in character and are useful in the field of rubber, plastics industries, etc.

    摘要： THERE IS DISCLOSED A PROCESS FOR HOMOPOLYMERIZING AT LEAST ONE DIOLEFIN OF THE GENERAL FORMULA:

    H2C=C(-Y1)-C(-Y2)=CH-R

    WHEREIN Y1 AND Y2 ARE SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND ALKYL RADICALS HAVING FROM 1 TO 4 CARBON ATOMS AND R IS SELECTED FROM ALKYL (INCLUDING CYCOALKYL), ALKARYL, ARYLALKYL AND ARYL GROUPS, CONTAINING FROM 1 TO 8 CARBON ATOMS, OR COPOLYMERIZING WITH AT LEAST ONE DIOLEFIN OF THE GENERAL FORMULA

    H2C=C(-Y1)-C(-Y2)=CH2

    WHEREIN Y1 AND Y2 ARE SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND ALKYL RADICALS HAVING FROM 1 TO 4 CARBON ATOMS, BY CONTACT, UNDER SOLUTION POLYMERIZATION CONDITIONS WITH A CATALYST COMPRISING (1) AN ORGANOALUMINUM COMPOUND FROM THE CLASS CONSISTING OF TRIORGANOALUMINUM AND DIOGRANOALUMINUM HYDRIDE COMPOUNDS, (2) AN ORGANOMETALLIC COMPOUND, THE METAL ION OF WHICH IS SELECTED FROM THE CLASS CONSISTING OF METALS OF GROUP III-B OF THE PERIODIC SYSTEM.

    摘要： A MULTI-STAGE EXOTHERMIC PROCESS, SUCH AS THE POLYMERIZATION OF BUTADIENE, IS CONTROLLED BY ADJUSTING THE HEAT REMOVAL FROM EACH STAGE IS RESPONSE TO TEMPERATURE MEASUREMENTS OF MATERIALS IN THE INDIVIDUAL REACTORS. THE CATALYST ADDITION TO THE FIRST REACTOR IS REGULATED IN RESPONSE TO THE HEAT REMOVAL FROM A DOWNSTREAM STAGE.
