Abstract:
A composition comprising at least one polymer and at least one plasticizer, whereina. the polymer is semi-crystalline and exhibits a processing temperature equal to or greater than 220Â° C., wherein the semi-crystalline polymer is a polyketone which is the condensation product of carbon monoxide with at least one aliphatic olefin; b. the plasticizer is an aromatic benzenesulphonamide represented by the general formula (I) in whichR1 represents a hydrogen atom, a C1-C4 alkyl group or a C1-C4 alkoxy group, X represents a linear or branched C2-C10 alkylene group, or a cycloaliphatic group, or an aromatic group, Y represents one of the groups OH or R2 represents a C1-C4 alkyl group or an aromatic group, these groups being unsubstituted or substituted by an OH or C1-C4 alkyl group; and c. the plasticizer is incorporated into the polymer by mixing in the molten state in an amount of 2% to 30% by weight with respect to the total weight of the composition.
