The invention provides a method of making a thermoset or thermoplastic gel composition containing a polymer with anhydride groups along the polymer backbone at least at outset of the fabrication process and an extender fluid, optionally including thermally conductive fillers. The method comprises reacting an anhydride-containing polymer with ester alcohol to form an ester-acid moiety, and then reacting with a multifunctional amine to form imide linkages. The resulting gel compositions are useful for sealing wires, vibration dampening, sporting goods, and toys.
L'invention concerne des compositions de gels thermodurcis ou thermoplastiques contenant un polymère. Des groupes anhydride se trouvent le long du squelette polymère au moins au début du processus de fabrication. Les compositions contiennent aussi un liquide diluant et, éventuellement, des charges de remplissage thermoconducteurs. Les compositions en question sont utiles dans les produits suivants: fils de plombage, dispositifs amortisseurs des vibrations, articles de sport et jouets.
