Binuclear metal hydride complexes as catalysts for the (co)polymerization of polar monomers

In functionalized linear alternating carbon monoxide copolymers of carbon monoxide and at least one 1-alkene (A), compound (A) is an aryl derivative substituted with at least one terminal allyl and/or homoallyl moiety and containing one or more polar groups, with the proviso that 4-allylanisole is excluded.

Functionalized carbon monoxide copolymers

The invention relates to the production of homopolymers, co-copolymers or block copolymers from cycloolefinic monomer units characterized in that polymerization occurs in the presence of a catalyst of general formula (I), and optionally in the presence of an additive, wherein the substituents and indices have the following meaning: M is a metal from group VIII B of the periodic table of elements; E,, E,are independently from each other an element from group V A of the periodic table of elements; Z is a bridging structural unit; Ar stands for annelated aryl units independent of each other; L,, L,stands for formally uncharged Lewis base ligands; X means monovalent or bivalent anions; k means 1 or 2; l, m, n represent 1 or 2, whereby m&times;n&equals;1.

Production of homocopolymers, co-polymers or block copolymers from cycloolefinicmonomer units

The present invention is a process of preparing copolymers of vinyl aromatic and olefinic monomers wherein the polymerization is carried out in a dispersion in the presence of a metallocene catalyst and a dispersion aid. The dispersion aid is a styrene-diene two-block copolymer or a styrene-diene three-block copolymer. The resultant polymer is useful as a fiber, film or molding.
