ABSTRACT OF THE DISCLOSURE Novel alternating block copolymer formed by melt blending a melt spinnable polyamide, such as nylon-6, and an alternating poly(dioxa-amide), such as a copolymer prepared from the mixture of caprolactam and the salt of adipic acid and 4,7-dioxadecamethylenediamine, is disclosed. The copolymer has utility as a fiber. The fiber, for example, resulting from melting blending of nylon-6 and the aforementioned alter- nating poly(dioxa-amide) has moisture absorption character- istics similar to that of cotton. Furthermore, the resulting fiber still maintains the other desirable properties of the major constituent, for example, nylon-6. -1-
