Process for treatment of nanoparticles of mineral filler for use in polymerization in the presence of nanoparticles
30 Nov 21
A process for treatment of nanoparticles of mineral filler for obtaining processed nanoparticles for use in polymerization in the presence of nanoparticles which includes the steps of (a) drying a mineral filler with an inert gas to remove catalyst poisons; (b) mixing the mineral filler dried obtained in step (a) with a swelling agent in a liquid state or near a critical state or in the supercritical state; (c) subjecting the swelling agent of the mixture obtained in step (b) to an endoenthalpic or isoentalphic phase change by altering the conditions of the temperature and/or pressure; (d) subjecting the nanoparticles of the mixture obtained in step (c) to contact of scavenging agent to react with catalyst poisons; then the mixture obtained in step (d) can be dried in a step (e) with an inert gas to remove sub-products from scavenging agent and catalyst poisons to obtain the treated nanoparticles.
