Abstract
The invention relates to an encapsulation composition for the storage or the confinement of waste which is toxic to health and/or the environment, comprising a resin composition containing at least one epoxy resin, and a hardening composition containing at least one polyamidoamine and at least one aromatic polyamine, said encapsulation composition having an aromaticity rate which is equal to, or higher than, 35%. The invention also relates to the use of said composition for encapsulating said waste.

An encapsulation composition for the storage or confinement of toxic waste, comprising:
- a resin composition containing at least one epoxy resin, and
- a hardening composition containing at least one polyamidoamine and at least one aromatic polyamine, wherein said polyamidoamine is a product of the reaction between one or more aliphatic polyethylene polyamine(s) and one or more mono- or polyunsaturated C12-C18 fatty acid(s),
- said encapsulation composition having a degree of aromaticity greater than or equal to 35%, said degree of aromaticity being defined as follows and expressed as a percentage;
- sum of the molecular weights of the aromatic rings present in the encapsulation composition and included in the polymer chain
- sum of the molecular weights of all of the components of the encapsulation composition.
