Abstract
The kinetics of NG migration has been studied for two groups of resins-Grou p I: PR-3, FUP-9 and EP-4 and Group II: PAP-1, CPAP-1 and CPAP-2. These uns aturated polyesters and chloropolyesters have been characterized for tensil e strength (TS), %-elongation and crosslink density. Further, diffusion coe fficient(D), NG migration at infinite time (M-infinity) and concentration p rofiles have also been determined. The data generated on TS, crosslink dens ity, D and M-infinity corroborate the fact that as the crosslink density in creases, D as well as M-infinity decrease.
