“…We used the following chemicals: dimethylacetamide available from Vekton (it was dehydrated and vacuum-distilled, with collection of the fraction boiling at 42oC and a residual pressure of 7 mm Hg); lithium chloride crystal hydrate (dehydrated at 400oC); sulfite cellulose (Svetogorsk Paper and Pulp Combine), DP = 996; crab chitin (manufactured by Vostok-Bor Joint-Stock Company, Dal'negorsk), M = 170 kDa, without ash and proteins; chitin from the North Sea shrimp, M = 135 kDa, with ash and proteins removed; polyvinylpyrrolidone (PVP) (samples with different molecular weights were prepared by radiation-induced polymerization [6]); and methyl cellulose with DP = 980 and degree of substitution 0.94 (laboratory synthesis).…”

“…In the course of the experiment, we monitored how the rate of the heat release due to the polymerization varies in time. The degree of conversion and reaction rate were calculated using the following heats of polymerization (kJ mol !1 ): 58.6 for N-VP [6] and 114.0 for TGM-3 [7].…”
