| abstract |
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. |
