Abstract The kinetics of emulsion polymerization of monomers MMA/BA was studied to investigate the effect of cross‐linkable monomer PPGDA. The results showed that by the incorporation of PPGDA, rate constant of reaction decreased. The IR and differential scanning calorimetry were used to characterize the presence of PPGDA in the synthesized polymers. These polymers were coated on glass panels and cured at appropriate temperature. The results showed that the polymer containing 15 wt % PPGDA had minimum value of Fickian diffusion coefficient, thus showing highest level of cross‐linking among all the polymers studied. © 2009 Wiley Periodicals, Inc.
