Abstract
The present invention relates to a composition that can be used to manufacture an impermeable, sealing, tight envelope, to a process for manufacturing an impermeable envelope, and to a tank. The composition of the invention comprises in % by weight relative to the total weight of the composition: from 70 to 90% of a monomer (I); from 0.1 to 1% of an activator (II), in which R is chosen from the group comprising CH, n being an integer chosen from 1 to 10; —OH; —OCH, n being an integer chosen from 1 to 10; and —NHR' where R′ is either CH, n being an integer chosen from 1 to 10, or an amine functional group; from 2 to 6% of a catalyst (III), in which X is chosen from the group comprising MgBr, MgI, Li and Na; and from 10 to 20% of an additive (IV), with: This composition can be used, for example, to manufacture elements that are impermeable to fluids, for example impermeable envelopes, for example that can be used in the manufacture of type IV tanks or hydraulic accumulators.
