ROTOMOLDING PROCESSES FOR POLY(ARYL KETONES) AND OTHER HIGH TEMPERATURE POLYMERS |
摘要 |
A method of manufacturing an article comprises rotomolding at least one polymer comprising a poly(aryl ketone), such as PEKK, under conditions effective to produce a rotomolded article having an impact value of at least 35 in-lbs. A rotomolding method comprises heating the mold for a period of time after the internal air temperature of the mold reaches the highest melting point of the at least one polymer. Methods also include using a PEKK powder with a bulk density of at least about 400 g/L. Rotomolded articles of the present invention have impact values of between about 40 in-lbs to about 95 in-lbs, and in particular embodiments greater than about 95 in-lbs. |
