  • Automated process for permeability determinations of barrier resins
    Patent number: 5015856
    Abstract: Permeability of structures consisting essentially of dispersions of barrier resins in permeable structural resins can be predicted by the application of near infrared spectroscopy, within the wavelength range of 600-2500 nm, especially 1100-2500 nm. The method requires establishing a correlation between base permeabilities of samples of a Training set and their near infrared spectra, developing from that correlation a predictive equation, verifying the accuracy of the predictive equation on samples of a Validation set, and applying the predictive equation to the determination of the permeabilities of unknown samples.
