Chemical modification of wool in aprotic swelling media

Chemical modification of wool in aprotic swelling media. Koenig, N. H. (WRRL, ARS, Berkeley, Calif., USA). J.Some commonly used reagents like 103-72-0 and 103-71-9 are used in this experiment. Appl. Polym. Sci., 21(2), 455-65 (English) 1977. CODEN: JAPNAB. DOCUMENT TYPE: Journal CA Section: 39 (Textiles) Polar nonhydroxyl org. solvents suitable for swelling wool during chem. modification with acylating-type reactants must have low mol. wt., should lack active H atoms, be highly polar, have a high boiling point, and exert a catalytic effect. Rates of modification by phenyl isocyanate [103-71-9], myristoyl chloride [112-64-1], and dodecenylsuccinic anhydride [25377-73-5] decreases in the order DMSO [67-68-5] >DMF [68-12-2] >1-methyl-2-pyrrolidinone [872-50-4] >4-butyrolactone [96-48-0]. Although reaction rates vary in these media, the final wool-reaction products are similar and do not include the solvent. .
