Abstract

La presente descripción proporciona un proceso. El proceso incluye (i) mezclar por fusión, en una extrusora, (a) una fase de poliolefina y (b) una fase acuosa en presencia de (c) al menos un dispersante seleccionado de un dispersante acrílico, un dispersante de poloxámero y combinaciones de estos; (ii) producir una tensión interfacial de 0.1 dinas/cm a 25 dinas/cm; (iii) formar una dispersión acuosa de poliolefina que tiene de 25% en peso a 90% en peso de contenido de sólidos de dispersión; y (iv) eliminar el agua de la dispersión acuosa de poliolefina para formar un polvo. El polvo tiene un tamaño de partícula promedio en volumen medio de 10 pm a 300 pm, una esfericidad de 0.92 a 1.0, una distribución de tamaño de partícula de 1 a menos de 2 y una densidad de partículas de 98% a 100%.
