Synthesis and characterization of polyethylene oxide and nylon‐6 copolymer in a fiber form

Abstract

AbstractA series of poly(ethylene oxide) (PEO) and nylon‐6 copolymers were synthesized through condensation reactions. The rheology of the prepared copolymers was tested using a capillary flow rheometer. The molar mass was investigated by performing basic analyses such as relative viscosity, gel permeation chromatograph, and amino‐end group analysis. Their thermal properties were examined by differential scanning calorimetry, and the crystalline structure was determined using wide‐angle X‐ray diffraction. The results obtained from partially oriented yarn indicated a dramatically conversion from the γ form to the α form. Following the draw texture process, the α form dominated all draw textured yarn. Once the segments of PEO were introduced into the nylon‐6 backbone, the moisture regain and qmax (warm/cool feeling) of the fabrics was enhanced remarkably. The surface resistivity of fabrics improved with increasing PEO content, which is mainly due to water absorption. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
