The purified polymer particles obtained by the process
of this invention can be blended in large lots to minimize
any slight variations in polymer characteristics such as
molecular weight, extractible content, and color.
The dry, blended polymer particles can be employed either
alone or in admixture with other polymers and additives
in various melt shaping operations such as injection mold~
ing and extrusion or spinning processes to form valu
able molded objects, filaments, films, and other products.
The puri?ed poly-E-caproamide obtained by the process
of this invention is especially well suited for the produc
tion of high quality, uniform filaments e.g. fine denier
filaments ‘for textile use, heavy industrial yarns such as
carpet yarn and tire yarn, etc.
