Abstract
Linear, crystalline, high M.W. polymers are formed from vinyl ethers of formula CH2=CHOR (R=alkyl, cycloalkyl or aryl, e.g. iso-Pr or isoBu) employing a catalyst comprising a complex of formula (C5H5)2TiX1XAlXY wherein C5H5 is cyclopentadienyl, X, X1 and Y are halogen atoms, or Y is alkyl up to C5. Specified complexes are (C5H5)2TiCl2AlCl2 and (C5H5)2TiCl2AlClEt. Use of the complexes in the polymerization of ethylene is also mentioned, but not claimed.ALSO:The invention comprises compounds of formula (C5H5)2TiX1XAlXY wherein C5H5 is cyclopentadienyl, X, X1 and Y are halogen atoms, or Y is C2-C5 alkyl. Specified compounds are (C5H5)2TiCl2AlCl2 and (C5H5)2 TiCl2AlClEt; they may be prepared by reacting a bis-cyclopentadienyl-titanium monohalide (e.g. chloride) (obtained from titanium trihalide and sodium cyclopentadiene) with either AlCl3 or AlCl2R1 (e.g. R1 = Et).
