Diffusion Coefficient of Diallyl Terephthalate Monomer into Thin Polymer Film

I. Hace, J. Golob and M. Krajnc

Attenuated total reflection infrared spectroscopy (ATR-FTIR) was used to measure diffusion of diallyl terephthalate monomer (DAT) into a polyDAT film. The assembly, consisting of an ATR crystal, polymer film and a monomer, was heated to a desirable interdiffusion temperature, the spectra thus obtained were deconvoluted and the diffusion coefficient of DAT monomer into polymer was calculated by least square regression technique at various temperatures from 21 °C to 50 °C and, various film thicknesses from 60 μm to 180 μm.
