摘要
A sinter powder (I) for selective laser-sintering comprises a polyamide having an excess of carboxylic end groups - a so-called regulated polyamide. Independent claims are included for: (1) a process for the production of sinter powder (I) by treatment of an unregulated polyamide with a carboxylic acid regulator; (2) a process for the production of molded articles by selective laser-sintering of the sinter powder (I) and; (3) the resulting molded articles.
