Abstract
Aqueous solutions of maleinized soybean oil MSO were evaluated as formaldehydefree reagents for cellulosic textiles The reactivity of cotton cellulose with MSO reagents having acid values of 156 and 230 mg KOH/g neutralized with aqueous ammonia in excess of functional groups was studied using diffuse reflectance infrared Fourier transform spectroscopy The acid value of aqueous ammonianeutralized MSO influenced the formation of protonated amide intermediates Cyclic anhydride and protonated amide functional groups were identified as reaction intermediates which resulted in carboxylic ester linkages between MSO and cellulose upon elevated temperature curingThe authors gratefully acknowledge the support received from the Cooperative State Research Education and Extension Service the US Department of Agriculture Agreement No 20013820210424 The authors also thank David Delatte for synthesizing the maleinized soybean oil investigated in this study
