    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： 1,138,299. Stereoblock butadiene polymers. BADISCHE ANILIN- & SODA-FABRIK A.G. 3 May, 1966 [4 May, 1965], No. 19366/66. Heading C3P. Stereoblock polymers are made by polymerizing butadiene with a Ziegler-Natta type catalyst comprising an alkyl metal compound and a compound of a transition metal of Groups IV to VIII, and whilst unreacted butadiene is still present in the polymerization mixture adding a catalyst of the same type but which converts butadiene into a polymer whose configuration is different to the configuration of the polybutadiene first prepared, and continuing the polymerization. In examples, effected in solvents, the following catalysts are used: (1) (C 2 H 5 ) 3 Al, AlBr 3 , and TiI 4 , followed by (C 2 H 5 ) 3 Al and VCl 3 , (2) as (1) but VCl 3 replaced by VCl 4 , (3) (C 4 H 9 ) 3 Al and TiCl 3 , followed by (C 2 H 5 ) 2 AlI and TiCl 3 , (4) (C 4 H 9 ) 2 AlCl and TiCl 3 , followed by (C 2 H 5 ) 2 AlI and TiCl 3 , (5) (C 2 H 5 ) 3 Al and TiCl 4 , followed by (C 2 H 5 ) 2 AlI and TiCl 3 , (6) (C 4 H 9 ) 3 Al and Ti(-OC 4 H 9 ) 4 , followed by (C 2 H 5 ) 3 Al and VCl 3 , (7) Cr triacetylacetonate and (C 4 H 9 ) 3 Al followed by (C 4 H 9 ) 3 Al, (8) Sn(C 4 H 9 ) 4 and ZrCl 4 , followed by amyl Na and TiCl 3 . The polymers may be sulphur vulcanized.

    摘要： The present invention relates to a process of conducting research using combinatorial techniques wherein metal-ligand compositions are synthesized and screened for reactivity in reactions of interest, particularly metal-ligand compounds which are suitable for use as catalysts. In the process, an array of different metal-ligand compositions is prepared by delivering a dissolved, soluble metal precursor and a metal-binding ligand to each reaction vessel or well in the array, where they may optionally be combined with an activator and/or other additives. The resulting metal-ligand composition in each vessel is then screened for reactivity in a chemical reaction of interest, particularly for catalytic activity in a polymerization reaction.
