The kinetics of NG migration has been studied for two groups of resins—Group I: PR‐3, FUP‐9 and EP‐4 and Group II: PAP‐1, CPAP‐1 and CPAP‐2. These unsaturated polyesters and chloropolyesters have been characterized for tensile strength (TS), %‐elongation and crosslink density. Further, diffusion coefficient (D), NG migration at infinite time (M ∞ ) and concentration profiles have also been determined. The data generated on TS, crosslink density, D and M ∞ corroborate the fact that as the crosslink density increases, D as well as M ∞ decrease.
