Abstract (en)
[origin: DE19917920A1] A process for the production of linear alternating copolymers of carbon monoxide and an olefin comprises copolymerization using a metal complex, a dissolution aid and a hydroxy compound. A process for the production of linear alternating copolymers of carbon monoxide and at least one 3-20 C olefinically unsaturated compound comprises copolymerization in the presence of (A1) a metal complex of formula (1), (B) a dissolution aid and (C) a hydroxy compound. G = 5-7 membered carbocyclic ring, optionally containing heteroatoms, -(CRb2)r<->, (CRb2)s-Si(Ra)2-(CRb2)t-, -A-O-B or -A-Z(R<5>)-B; R<5> = H, a functional group containing atoms of Group IVA, VA, VIA or VIIA, substituted 1-28C alkyl, 3-14C cycloalkyl, 6-15C aryl, or an alkyl aryl with 1-20C alkyl and 6-15C aryl, N(Rb)2, -Si(Rc)3 or formula (2); q = 0-20; A, B = -(CRb2)r'-, -(CRb2)s-Si(Ra)2-(CRb2)t-, -N(Rb)-, a corresponding ring system or together with Z forms a heterocycle; Ra = 1-20C alkyl, 3-10C cycloalkyl, 6-15C aryl or an alkylaryl having 1-10C alkyl and 6-15C aryl, optionally substituted; Rb = as Ra, H or Si(Rc)3; Rc = 1-20C alkyl, 3-10C cycloalkyl, 6-15C aryl or an alkylaryl having 1-10C alkyl and 6-15C aryl, optionally substituted r = 1-4; r' = 1 or 2; s, t = 0-2; s+t = 1-3; Z, E<1>, E<2> = Group VA element ; M = Group VIIIB, IB or IIB element ; R<1>-R<4> = 2-28C alkyl, 3-14C cycloalkyl, 6-15C aryl or an alkylaryl having 1-28C alkyl and 6-15C aryl, provided at least one of R<1>-R<4> contains an OH, amine, or ionic group; L<1>, L<2> = charged or neutral ligand; X = mono- or multivalent anion; p, m, n = 0-4; and p = m \* n. An Independent claim is also included for a process for the production of the copolymer in the presence of (A1.1) a metal M in salt or complex salt form (A1.2) a chelate ligand of formula (3), (B) a dissolution aid and (C) a hydroxy compound.
