    摘要: 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).

    摘要: Super-halogenated unsaturated polyesters having average molecular weights of between 300 and 3,000, comprising units derived from at least one .alpha.-epihalohydrin and from maleic anhydride and optionally from another cyclic organic anhydride, possessing a halogen content arising from super-halogenation of between 1 and 35% by weight and the process for their manufacture which is characterized in that maleic anhydride, alone or mixed with another cyclic organic anhydride, is copolymerized with at least one .alpha.-epihalohydrin in molar ratios of epihalohydrin to anhydride(s) of between 1:1 and 2:1, in the presence of a titanium tetrahalide, the halogen being preferably chosen from the group consisting of chlorine and bromine.
