    摘要: A process for polymerizing unsaturated monomers is disclosed. The process comprises polymerizing, in the presence of a late transition metal catalyst (LTMC), a variety of unsaturated monomers which are traditionally, some of which are exclusively, made by free radical polymerizations. The LTMC polymerization provides the polymer with improved properties such as no free radical residue and narrow molecular weight distribution.

    摘要: The present invention provides a process for producing a crosslinkable styrene or styrene derivative polymer having narrow molecular weight distribution by radical polymerization of a styrene or styrene derivative monomer and other comonomer, wherein the polymerization is conducted in the presence of a catalyst system composed of a free radical compound and a radical polymerization initiator. With the present process, a heat- or photo-crosslinkable styrene or styrene derivative polymer having excellent rheology controlling ability and excellent reaction efficiency of a functional group can be obtained.

    摘要: The invention relates to copolymers containing on average 1.25 to 30 functional groups per molecule and a number average molecular weight of 1500 to 6000, which copolymers can be prepared by free-radical solution polymerization at 130.degree. to 200.degree. C. from 5 to 25% by weight of vinyl ester, 10 to 50% by weight of vinyl aromatic, 10 to 40% by weight of functional, monomers and, if desired further monomers, in which the vinyl ester is initially introduced and the remaining monomers are metered in for all monomers over a monomer addition period which is of the same length in the following manner: The amount of acrylate monomers added per unit of time remains constant. The amount of vinyl aromatic added over the first third of the monomer addition period is 15 to 30% by weight, the amount added over the second third is 25 to 40% by weight, and the amount added over the last third is 35 to 60% by weight, each relative to the total amount of vinyl aromatic. The copolymer obtained is, if desired, reacted with compounds containing a group which is reactive towards the functional groups of the copolymer and at least one crosslinkable group.
