    • A process for the preparation of linear alternating copolymers of carbon monoxide and an ethylenically unsaturated compound by polymerizing the monomers in the presence of a suitable catalyst system, one or more components present in the reaction mixture being contaminated with alkali(ne earth) metal salt(s), which process involves a treatment by which at least part of the alkali(ne earth) metal salt is removed such that the total amount of alkali(ne earth) metals present in the copolymerization product is less than 1 part per million by weight; a copolymer composition comprising said copolymer, an alkali(ne earth) metal salt contaminant and a stabilizing quantity of a substance which is able to bind at least part of the alkali(ne earth) metal salt. A method for melt processing said copolymer, wherein the copolymer which contains an alkali(ne earth) metal salt contaminant is mixed with a stabilizing quantity of a substance which is able to bind at least part of the alkali(ne earth) metal salt, the substance being other than a hydroxyapatite or a zeolite-type trivalent metal silicate, and wherein the resulting mixture is melt processed.
    • 通过在合适的催化剂体系的存在下聚合单体来制备一氧化碳和烯键式不饱和化合物的线性交替共聚物的方法,反应混合物中存在的一种或多种组分被碱(碱土金属)金属盐 s),该方法涉及去除至少部分碱金属盐(ne earth)金属盐的处理,使得共聚产物中存在的碱金属(ne土)金属的总量少于百万分之一 ; 包含所述共聚物,碱金属(ne土)金属盐污染物和稳定量的能够结合至少部分碱金属盐的物质的共聚物组合物。 一种用于熔融加工所述共聚物的方法,其中将含有碱(镍)金属盐污染物的共聚物与稳定量的物质混合,所述物质能够结合至少一部分碱金属(ne)金属盐, 物质不是羟基磷灰石或沸石型三价金属硅酸盐,并且其中所得混合物被熔融加工。
