Abstract The aim of this study was the synthesis of three different epoxy compounds based on naphthalene-2,7-diol (2,7-NAF.EP, 2,7-NAF.WEP, 2,7-NAF.P.EP) and then their cross-linking by triethylenetetramine (TETA). All epoxides were prepared by the reaction of naphthalene-2,7-diol with epichlorohydrin but under different conditions and with other catalysts. The structures of the obtained compounds before and after the cross-linking reactions were confirmed by the attenuated total reflectance Fourier transform infrared spectroscopy (ATR/FT-IR). The ATR/FT-IR spectra of cross-linked compounds show disappearance of the C–O–C bands (about 915 cm−1) derived from the epoxy groups. DSC and TG/DTG measurements indicated that the obtained materials possess good thermal resistance; they are stable up to about 250 °C. The hardness of the cross-linked products was determined using the Shore D method. The highest value of hardness was obtained for the 2,7-NAF.EP-POL. Additionally, the UV–Vis absorption spectra of the obtained polymers were registered and evaluated.

Recovery Angle

2-(Diethylamino)ethyl cotton celluloses in the form of print cloth and at three levels of nitrogen have been quaternized and converted to the strong bases. Studies were made of internally catalyzed reactions of these cotton cellulose quaternary ammonium hydroxides with divinyl sulfone at room temperature in a “wet-cure” and with bis-(2-hydroxyethyl) sulfone in a “bake-cure.” Moderate levels of conditioned wrinkle-recovery angles and high levels of wet wrinkle-recovery angles result from the “wet-cure” reaction. The wrinkle-recovery angles of these modified cotton celluloses are compared to those of the corresponding cotton celluloses cross-linked by conventional external catalysis. The internally catalyzed fabrics from the “wet-cure” are particularly interesting among these compositions with regard to (a) the developed levels of wrinkle-recovery angle, (b) the capability of these compositions to develop high conditioned wrinkle-recovery angles as a result of recure in a “bake-cure” in the absence of external catalysis, and (c) the evidence of mobility of the cross links (i.e., reversibility of the cross-linking reaction followed by reformation of new or old cross linkages) at elevated temperature.
