Abstract (en)
[origin: DE19812124A1] Preparation of copolymers from unsaturated olefinic monomers and nonpolar olefins in which none or only a very small part of homopolymer is accumulated, in the presence of transition metal catalysts. Preparation of copolymers from unsaturated olefinic monomers and nonpolar olefins in which none or only a very small part of homopolymer is accumulated. The monomers are reacted with shielded aromatic monohydroxy compounds having sterically hindered groups or with a N-oxyl radical having sterically hindered groups in the presence of a transition metal compound of formula (Ia) or (Ib). R<1>-R<4> = H, 1-10C alkyl, 1-10C partially or perhalogenated alkyl, 3-10C cycloalkyl, 6-14C aryl, with functional groups based on Group IVA, VA, VIA, and VIIA elements, partially or persubstituted 1-14C aryl or 4-13C heteroaryl; X = alkylaryl, with 1-10C in alkyl and 6-14C in aryl residues, or Si(R<6>)3, where R<1> and R<4> are not H. Alternatively, R<1> and R<2> together with Ca and Na or R<3> and R<4> together with Cb and Nb = a five-, six-, or seven-membered aromatic or aliphatic optionally substituted hetero ring, or R<2> and R<3> together with Ca and Cb = a five-, six-, or seven-membered aromatic or aliphatic optionally substituted carbo- or hetero-ring; R<5> = H, 1-10C alkyl, 3-10C cycloalkyl, 6-14C aryl, X or Si(R<6>)3; R<6> = 1-10C alkyl, 3-10C cycloalkyl or X; m = 0 or 1; M = a Group VIIIB element; Q = acetonitrile, benzonitrile, , linear 1-4C alkyl ester, linear or cyclic alkyl ether, dimethylsulfoxide, dimethylformamide, hexamethylphosphoric acid triamide or halogenide; T = chloride, bromide, or iodide, or 1-20C alkyl which in the beta-position to the metal center has no H, and if necessary a 1-4C alkyl ester end or nitrile end group is available, or Q and T together form a C-3 alkylene chain with a a 1-4C linear alkyl ester or nitrile end group; A = non-coordinated or poorly coordinated anion; and n = 0, 1, 2 or 3.
