1. Flexible compositions based on vinyl chloride polymers and on poly-ε
- -caprolactone, consisting essentially of vinyl chloride polymers chosen from the copolymers of vinyl chloride and of alkyl acrylates in which the alkyl radicals consist of linear or branched chains containing from 1 to 10 carbon atoms and of poly-ε
-caprolactone wherein the initial Shore A hardness of the compositions does not exceed 85.

Abstract
The compositions contain, as vinyl chloride polymers, copolymers of vinyl chloride and of alkyl acrylates in which the alkyl radicals, consisting of linear or branched chains, contain from 1 to 10 carbon atoms and have an initial Shore A hardness not exceeding 85. They are suitable for the production of very diverse flexible articles, especially in the medical field (pouches for blood and for physiological fluids), the motor vehicle field (various profiles and seals) and the building industry (sealing sheets).
