Abstract
Abstract New polymers of carbon monoxide with ethene and with one or more other olefinically unsaturated hydrocarbons (A), with less than 20 carbon atoms characterized in that, a) the polymers have a linear structure, b) they consist of units -CO(C₂H₄)- and units -CO-(A)-, c) said units -CO-(A)- are randomly distributed, and d) the polymers have a melting point of between 150 and 245 °C.
