Abstract: The present invention relates to a stable storable composition for the chemical grafting of at least one filler comprising a hydroxyl group, onto a polymer. The composition according to the invention comprises at least one organic carboxylic acid comprising a carbon/carbon double bond that forms a resonance structure with the carbon/oxygen double bond of the carboxyl group, said composition being characterized in that it comprises a dispersing agent of the polyethylene oxide-based block polymer or copolymer type. The invention also relates to a process for chemical grafting of an organic acid onto a filler comprising at least one hydroxyl group, using said composition, so as to obtain a polymerizable liquid mixture.

Abstract: The present invention relates to a prefabricated modular building composed of a roof, a floor and vertical panels assembled together, said building further comprising four vertical corner elements placed respectively at the four corners of the building, extending over the whole height of the vertical panels and forming ties between the roof and the floor, and vertical securing members anchored, at one of their ends, in one of the horizontal elements (roof or floor), passing through each corner element and blocked, at their other ends, in the other horizontal element (floor or roof).

Abstract: A prefabricated modular building capable of being dismantled and re-used. This building has a roof and a floor, each made in one piece from molded plastic material and each having a peripheral rib, which serves as a strengthening member and as a housing for services.
