This invention provides a viscous, shape conforming gel, comprising between about 1% and 50% by weight (dry) of a plurality of polymeric nanoparticles suspended in a liquid or liquids, at least one of which is polar. The plurality of polymeric nanoparticles contained in the gel have an average diameter of less than 1 micrometer and are comprised of an effective amount of polymeric strands each of which is obtained by polymerization of an effective amount of a monomer or two or more monomers in a polar liquid or a mixture of two or more miscible liquids, at least one of which is polar, and an effective amount of a surfactant to stabilize the plurality of gel particles, thereby forming a suspension of gel particles.
La présente invention concerne un gel visqueux de conformation de forme, comportant entre environ 1% et 50% en poids (sec) d'une pluralité de nanoparticules polymériques suspendues dans un liquide ou des liquides, dont au moins un est polaire. La pluralité de nanoparticules polymériques contenues dans le gel présentent un diamètre moyen inférieur à 1 micromètre et comprennent une quantité efficace de brins polymériques obtenus par la polymérisation d'une quantité efficace d'un monomère ou d'au moins deux monomères dans un liquide polaire ou un mélange d'au moins deux liquides miscibles, dont au moins un est polaire, et une quantité efficace d'un tensioactif pour stabiliser la pluralité de particules de gel, formant ainsi une suspension de particules de gel.
