| 27 | Process for reducing surface aberrations | US10561209 | 2004-06-16 | US20070164467A1 | 2007-07-19 | David Smith; Michael Andrews |
| The processes and resins of the present invention allow the extrusion of polymer products, such as polymer films, that have a reduced occurrence of surface aberrations, e.g., surface melt fracture and/or haze bands and/or haze. Preferably, the polymer products produced in accordance with the present invention are substantially free of surface aberrations even when manufactured under conditions of high sheer stress such as those conditions that occur at commercial production rates. In part, the present invention provides processes for polymer extrusion wherein the resins employed are treated using heat in an atmosphere sufficient to substantially eliminate the tendency to create surface aberrations. The resins can have reduced or substantially eliminated concentrations of low molecular weight components. In some embodiments, both the polymer resins and the extruded polymer products have reduced concentrations of processing aid(s), e.g., the polymer resins and the extruded polymer products are substantially free of processing aid(s). | ||||||

| 37 | PROCESS FOR PREPARING FOOD CONTACT GRADE POLYETHYLENE TEREPHTHALATE RESIN FROM WASTE PET CONTAINERS | EP00965627 | 2000-09-18 | EP1244540A4 | 2002-11-06 | KOSIOR EDWARD |
| A process for preparing food contact grade PET from a waste stream containing PET and non PET materials is disclosed. The process involves the steps of sorting at least some of the non PET materials from the waste stream, followed by dividing the PET containers into flakes of preferable maximum size approximately 10mm, followed by washing the flakes in a hot aqueous medium containing alkaline materials and surfactants, preferably non-ionic, to remove particulate and absorbed contaminants from the surfaces of the flakes. This step is followed by de-watering and then drying the flakes to a moisture content of 0.1 % w/w maximum, and more preferably 0.01 % w/w maximum. The next step involves removing absorbed contaminants and moisture by heating and vigorously mixing the flakes under vacuum, preferably 1-10 millibar, more preferably 2-7 millibar and at a temperature less than the melting point of PET, preferably in the range 170-220 DEG C for at least 30 minutes, preferably at least 60 minutes. The final step involves melting the flakes in a screw extruder equipped for vacuum processing and extruding the molten material to form strands that are pelletised. | ||||||
