The chemical covalent bonding of trimethylolmelamine (TMM) with cotton cellu lose produced under wet and dry curing conditions has been further investigated. The extent of chemical reaction with cellulose and the location of substituents on the anhydroglucose units were determined by an analytical scheme embodying chemical modification, complete hydrolysis, and gas chromatography of the analysis products. High temperature (160°C) curing gave rise to much greater extents of reaction with cellulose than curing under wet conditions. In the case of TMM, reaction at the primary. hydroxyl (C6) predominated at DS 0.16, whereas the major reaction of a methylated TMM having DS 0.30 occurred at C2.
