ABSTRACT:
Novel block copolymer formed by melt blending a melt spinnable polyamide, such as nylon-6, and a poly(dioxa-arylamide), such as poly(4,7-dioxadecamethylene terephthalamide) (also known as N-30203-T), is disclosed. Said copolymer has utility as a fiber. The fiber of a block copolymer, for example of nylon-6 and said poly(dioxa-arylamide) which is also known as N-30203-T/6, has superior moisture absorption and initial modulus characteristics than that of nylon-6. Furthermore, resulting fiber still substantially maintains the other desirable properties of the major constituent, for example, nylon-6.
