摘要:
The present invention falls in the membrane separation methods field and in particular applies to the purification of C2 or C3 olefins. The present method more particularly separates propylene from a mixture containing other C3 hydrocarbons such as propane. The membranes used in the method according to the present invention are membranes based upon vitreous polymers whose unit contains a bis-phenyl-9,9-fluorene substituent.

摘要:
The invention relates to a novel composite material comprising at least one crystallised hybrid organic-inorganic material shaped in the form of an extruded product using a binder formulation comprising at least one polymer binder, said material having a high crystallised organic-inorganic hybrid material content. The invention also relates to the method for the production of said material.
摘要:
The invention relates to a chemically gelled curable composition based on epoxy-amine resins and on ionic liquids. The invention advantageously applies to energy accumulating systems, in particular electrochemical systems. The curable composition according to the invention may in particular constitute an electrolyte that can be used in a battery for a hybrid or electric vehicle.
