PROCESS AND METHOD FOR COMPATIBILIZATION OF MULTI-COMPONENT POLYMERIC BLENDS AND COMPOSITES BY DEGRADATION.

摘要

The present invention relates to a process for compatibilization of multicomponent polymer blends from waste plastic products characterized by comprising the following steps: A) Depositing in a primary extruder or furnace a mixture of waste plastic products. B) Incorporating into said primary extruder at least one ox-degrading additive in an amount of up 1% to 5% related to the total weight of waste plastic products. The operating temperature of said primary extruder or furnace is of up between 350°C to 400°C and with a residence time of up between 1mins to 2 mins, thus generating fluid and melt polymer mixture. C) Depositing the fluid and molten polymer mixture of the primary extruder into a secondary extruder at a temperature of up between 200°C to 300°C and with a residence time of up between 1mins to 2 mins. D) Filtering the resulting product at the exit of the said secondary extruder using a mesh system with perforations of approximately 0.1 mm to remove contaminants and produce as a resulting product, compatibilized cast plastic profiles.
