  • PRODUCING SEMI-CRYSTALLINE PULVERULENT POLYCARBONATE AND USE THEREOF IN ADDITIVE MANUFACTURING
    Publication number: 20230272162
    Abstract: Ways of preparing a partially crystalline polycarbonate powder are provided that include dissolving an amorphous polycarbonate in a polar aprotic solvent to form a first solution of solubilized polycarbonate at a first temperature. The first solution is then cooled to a second temperature, the second temperature being lower than the first temperature, where a portion of the solubilized polycarbonate precipitates from the first solution to form a second solution including the partially crystalline polycarbonate powder. Certain partially crystalline polycarbonate powders resulting from such methods are particularly useful in additive manufacturing processes, including powder bed fusion processes.
    Type: Application
    Filed: March 3, 2020
    Publication date: August 31, 2023
