| abstract | 873,663. Polymerization catalysts. BURKE, O. W. April 25, 1957 [Feb. 19, 1957], No. 1234/61. Divided out of 873,656. Class 1(1). [Also in Group IV(a)] A polymerization catalyst comprises a multimetallated organic compound "1" and Friedel Crafts compounds "2b" with or without a modifying polar compound "2a" and/or a carrier component "3". Component "1" is defined as containing at least two metal atoms bonded to the same hydrocarbon moiety by carbon-metal bonds; said moiety may be polymeric or non-polymeric, while the metal atoms are selected from Li, Na, K, Rb, Cs, Cu, Ag, Be, Mg, Ca, Sr, Ba, Zn, Cd, Hg, B, Al, Sc, Yb, La, Ga, In, Tl, Ti, Zr, Th, Ge, Sn and Pb. Component "2b" comprises mixed halides obtained by burning in halogen gases or vapours the ferro-alloys of metals of Periodic Group IV, V, VI, iron Group VIII, and Mn, with or without reductive after treatment with metal powders, metal hydrides, metal carbides and/or hydrogen and the said halides may be partially reacted with oxygen water and/or reactive organic compounds such as alcohols. Component "2a" consists of organic donor compounds containing one or more of O, N, S, Se, Te, halogens; various classes of such compounds being mentioned and a number of peroxides and azo-compounds being also specified; such donor compounds include those in which active hydrogen atoms have been replaced by metals. Component "3" is an organic or inorganic solid not detrimental to the polymerization and including shaped materials and carbon. Many metals and acid radicals suitable as constituents of this component are listed as are many specified oxides. The usual hydrocarbons and their halogenated derivatives are mentioned as solvents for catalyst formation and polymerization. In examples, ethylene is polymerized in presence of catalysts comprising (1) p-xylene di-Na, NaCI, Fe-Cb chlorides; (2) p-xylene di-Na, NaCl, Fe-Mo chlorides; (3) p-xylene di-Na, NaCl, Fe-W chlorides; (4) α-methylstyrene trimer tri-Na, NaCl, Fe-V chlorides. Also specified as alloys from which "2b" can be derived are Fe-Mn and Fe-Cr. The monomers which in general may be polymerized with the above catalyst contain at least one Polymerizable ethylenic and/or acetylenic linkage; the monomer may itself form the diluent as an alternative to using a separate diluent. Numerous monomers are listed in the Specification; these include the following types:-α-olefines; chloro, fluoro, chlorofluoro and bromo olefines including chloro and bromo aryl and alkaryl olefines; aryl and alkaryl olefins; conjugated dienes and trienes. Specifications 873,658 and 873,660 also are referred to. |
