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).
