中文摘要 | a novel method was developed to determine the ultra-low glass transition temperature (t-g) of materials through physical blending via differential scanning calorimetry. according to the fox equation for polymer blends, a blend of two fully compatible polymers has only one t-g. the single t-g is a function of the t(g)s of the two simple polymers. thus, the ultra-low t-g of one material can be obtained from the t(g)s of another polymer and their blends. the error of t-g measurements depends on the measurement error of the t(g)s for the blends and another polymer. the method was successfully applied to determine the t(g)s of acetyl tributyl citrate (atbc), tributyl citrate (tbc) and poly(ethylene glycol)s (peg)s with different molecular weights. the t(g)s for atbc, tbc, peg-4000 and peg-800 were -57.0 degrees c, -62.7 degrees c, -76.6 degrees c and -83.1 degrees c, respectively. for all the samples, the standard deviation of measurements was less than 3.3 degrees c, and the absolute error of measurements was theoretically not more than 5.3 degrees c. these results indicate that this method has acceptable precision and accuracy.
