Beschreibung
Zusammenfassung:	The invention concerns a composition useful for making a sealing envelope, and a method for making a sealing envelope, and a reservoir. The inventive composition comprises in wt. % based on the total weight of the composition: 70 to 90 % of a monomer (I); 0.1 to 1 % of an activator (II), wherein R is selected from the group consisting of CH, n being an integer selected from 1 to 10; -OH; -OCH, n being an integer selected from 1 to 10, or an amine function; 2 to 6 % of a catalyst (III), wherein X is selected from the group comprising MgBr, MgI, Li and Na; and 10 to 20 % of an additive (IV), with (I) (II) (III) (IV). Said composition is useful, for example, for making fluid-impermeable elements, for example sealing envelopes, for example useful in the manufacture of type IV reservoirs or hydraulic accumulators.
