Copolymer compositions comprising an alternating copolymer of carbon monoxide and one or more lubricating additives of the general formula X-R, in which X represents a polar moiety which is one of the following groups: (a) alcoholic -OH, (b) -O-R', (c) -CO-O-R', (d) -O-CO-R', and (e) -CO-OH, in which R' represents an alkyl group having up to 4 carbon atoms which may be substituted with 1 to 3 groups selected from (1) -O-R", (2) -CO-O-R" and (3) -O-CO-R", wherein each R", independently, represents hydrogen or an alkyl group having up to 4 carbon atoms, and R represents a monovalent hydrocarbyl radical having 5 to 30 carbon atoms which is attached to (one of) the polar group(s); and a process for improving flow properties of alternating copolymers of carbon monoxide comprising the addition thereto of one or more of said lubricating additives.
由一氧化碳与一种或多种通式为 X-R 的润滑添加剂交替共聚而成的共聚物组合物,其中 X 代表极性基团,该极性基团为以下基团之一:(a)醇-OH,(b)-O-R',(c)-CO-O-R',(d)-O-CO-R'和(e)-CO-OH,其中 R'代表具有最多 4 个碳原子的烷基,可被 1 至 3 个选自(1)-O-R"、(2)-CO-O-R "和(3)-O-CO-R "的基团取代、其中每个 R "独立地代表氢或具有最多 4 个碳原子的烷基,R 代表具有 5 至 30 个碳原子的单价烃基,该烃基连接到(其中一个)极性基团上;以及一种改善一氧化碳交替共聚物流动特性的工艺,包括在其中加入一种或多种所述润滑添加剂。
