  • Plasticized polymer compositions
    Patent number: 6624218
    Abstract: The invention relates to compositions comprising at least one polymer and at least one plasticizer, in which compositions the polymer is semi-crystalline and exhibits a processing temperature equal to or greater than 220° C., preferably 250° C., and the plasticizer is an aromatic benzenesulphonamide represented by the general formula (I) in which R1 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 representing a C1-C4 alkyl group or an aromatic group, these groups optionally themselves being substituted by an OH or C1-C4 alkyl group.
