Publication number: 20210292544Abstract: The invention relates to heat treatment of polymorphic semicrystalline or crystallizable polymers to increase the content of the highest melting crystalline form. Such heat treatment results in a polymer powder that has a consistent, uniform melting range, improved flow and improved durability of the powder particle size for applications that require powder flow at elevated temperatures. In addition to improved powder properties, the articles produced from the powders also exhibit better physical properties in both appearance and in mechanical properties. Thus the invention also includes polymer powders and articles produced by the described processes.Type: ApplicationFiled: June 7, 2021Publication date: September 23, 2021Inventors: Christopher A. BERTELO, Manuel A. GARCIA-LEINER, Anthony DECARMINE, Scott F. DEFELICE

Patent number: 10899047Abstract: 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.Type: GrantFiled: March 5, 2013Date of Patent: January 26, 2021Assignee: Arkema Inc.Inventors: Manuel A. Garcia-Leiner, Bruce Clay
