Abstract
Thermoanalytical scanning has been carried out on a cross-linking agent, trimeth ylolmelamine, which is typical of the reactants used for imparting durable-press charac teristics to cotton. This compound was investigated by itself and in various combinations with glucose and cellobiose. Catalyzed and noncatalyzed conditions were compared. A variety of thermally induced processes were revealed as occurring in the temperature range 100-200°C, and it was shown that zinc nitrate catalyst can radically change the course of the reactions. By means of differential thermal analysis, it was found possible to distinguish between trimethylolmelamine homopolymerization and the reaction between this compound and carbohydrate hydroxyl groups.
