The invention is related to an olefin-carbon monoxide-vinyl monomer terpolymer composition which is derived from an olefin feed and a synthesis gas feed and at least one vinyl monomer feed. The invention is also related to a method for preparing olefin-carbon monoxide-vinyl monomer terpolymers by heating an olefin feed, a synthesis gas feed and at least one vinyl monomer feed in the presence of a free radical polymerization initiator. More particularly, the synthesis gas feed comprises predominantly carbon monoxide and hydrogen. The terpolymers of the invention are useful as polyvinyl chloride plasticizers.

L'invention concerne une composition de terpolymères de monomère de vinyle- monoxyde de carbone-oléfine, qui est dérivée d'une charge d'oléfine et d'une charge de gaz de synthèse et d'au moins une charge de monomère de vinyle. Cette invention concerne également un procédé de préparation de terpolymères de monomère de vinyle-monoxyde de carbone-oléfine, consistant à chauffer une charge d'oléfine, une charge du gaz de synthèse et au moins une charge de monomère de vinyle en présence d'un initiateur de polymérisation radicalaire. Plus spécifiquement, la charge du gaz de synthèse renferme surtout du monoxyde de carbone et de l'hydrogène. Les terpolymères de cette invention sont utilisés comme plastifiants de chlorure de polyvinyle.
