POLYMER POWDER CONTAINING BLOCK POLYETHER AMIDE, ITS USE IN MOLDING METHOD AND MOLDED ARTICLE PRODUCED FROM THE POLYMER POWDER

摘要

PROBLEM TO BE SOLVED: To provide polymer powder from which impact-resistant molded articles can be produced by a processing method capable of being realized as well as possible.

SOLUTION: This polymer powder is used for a method for introducing electromagnetic energy into a selected range of a powder layer each time to melt, thereby producing a laminated molded article. The powder has at least one block polyether amide comprising an oligoamidedicarboxylic acid and a polyetheramine.
