Abstract
Un método de formación de microcápsulas con gran resistencia al calor y baja permeabilidad, que consiste en formar películas de pared de una resina de urea-formaldehido alrededor de gotitas individuales de una solución oleosa hidrófoba mediante una reacción de polimerización de urea y formaldehido en presencia de alcohol polivinílico carboxilado.
