Abstract

La présente invention concerne un procédé de production de particules polarisant la lumière comprenant la mise en réaction d'un précurseur apte à former des particules de polyhalogénure à partir d'iode élémentaire, et d'un acide d'hydrohalogénure ou d'un halogénure d'ammonium, de métal alcalin ou alcalino-terreux, la granulométrie moyenne ou médiane du précurseur étant inférieure à 1 micron.
