  • Water absorption and moisture permeation properties

    2016-3-1 · The ESR values of the three polymers, Ch/poly(AAm-co-IA) 575, Ch/poly(AAm-co-IA) 1150 and Ch/poly(AAm-co-IA) 1920 were 13.85, 18.5 and 8.06 g/g, respectively. It means that as the milli moles of IA increase from 575 to 1550, the ESR increases due to increased partial ionization of first carboxylic groups of IA, thus causing more relaxation of poly(AAm-co-IA) chains and accommodating …
