63293-2860 ABSTRACT Novel copolymers of carbon monoxide with ethene and with one or more other .alpha.-olefinically unsaturated hydrocarbons, prepared by the copolymerization of carbon monoxide with ethene and with one or more unsaturated hydrocarbons (A) which contain fewer than 20 carbon atoms and have the general formula CH2=C(R6)(CHR7R8), wherein R6 represents a hydrocarbyl group and R7 and R8 represent hydrogen and/or hydrocarbyl groups. The co- polymers have a linear structure and they are made up of units of the formula -CO-(C2H4)- and units of the general formula -CO-(A')-, wherein A' represents a monomer unit originating in a monomer A used. The copolymers have melting points of between 150 and 245°C which makes their processing easier. Consequently, they are useful in manufacturing of shaped objects consisting at least partly of these copolymers.
