Abstract
Un proceso para preparar composiciones de poliéster/partículas plaquetarias que exhiben dispersion mejorada, el cual comprende las etapas dedispersar por lo menos un material arcilloso en un polímero disipable en agua para formar una dispersion de partículas plaquetarias; introducir dichadispersion en un poliéster; y mezclar con extrusion dicha dispersion y poliéster para formar una composicion mixta de partículas plaquetarias-poliéster en la cual dichas partículas plaquetarias comprenden principalmente partículas plaquetarias y tactoides.A process for preparing improved dispersion exhibiting polyester / platelet compositions, which comprises the steps of dispersing at least one clay material in a water-dissipatable polymer to form a dispersion of platelet particles; introducing said dispersion into a polyester; and extrusion mixing said dispersion and polyester to form a mixed platelet-polyester particle composition in which said platelet particles mainly comprise platelet and tactile particles.
