Abstract

A method for coating powders with nylon by mixing the powder with the nylon and a solvent for the nylon, precipitating the nylon out of solution and coating the powder particles, and separating the coated powder substantially in the form of agglomerates of individually coated particles. The coated powder can then be readily compressed to form a shaped structure, such as, a molded article. A nylon coated powder especially suitable for conversion into shaped structures by melt processes, such as, injection molding or melt extrusion, is obtained by incorporating an organic polymer modifier into the nylon coated powder.
