Abstract
The present process involves incorporating together, ie mixing, the dry salt and the dried particles of the polyamide at a temperature in the range of the melting point of the component of higher melting point and below the amide exchange temperature. Of a mixture of the meltable, spinnable polyamide and the homopolymer that would result from the polymerization of the salt. The mixing at high temperature proceeds until substantially all of the salt and the polyamide have been converted into a block copolymer. The resulting block copolymer can be converted into a fiber or monofilament which can then be converted into yarn or cloth, for example. (Machine-translation by Google Translate, not legally binding)
