Answer to Question #93026 in Organic Chemistry for Tanmay

Question

(1) The reaction of n-methylol compounds with cellulose is an acid catalyzed reaction?
(2) high drying temperature helps in reducing the Migration of chemicals?
(3) if the extent of crosslinking is increased, the bending length of the treated fabric would increase?

Answer 1

(1) Catalysis (acid) breaks the carbon/oxygen linkage of the N-methylol groups, and a reaction takes place with the hydroxyl groups of thecellulose with the discharge of water. 

(2) Thermopassivation is measured by the difference between the discharge potential of thermopassivated and unpassivated positive plates. 

(3) Cross-linked polymers, such asthermosets and elastomers, behave completely different than their counterparts, thermoplastic polymers. In cross-linked systems, the mechanical behavior is also best reflected by the plot of the shear modulus versus temperature.
