With reference to the analysis of a thermomechanical curve obtained in the usual way it is shown that by virtue of its sharply expressed dependence on time in the region of the glass-transition point the strain is not a sufficiently convenient criterion for estimating the glass-transition temperature of a polymer. A modified method of constructing the thermomechanical curve, which takes this factor into account, is proposed. The possibility of using this method to investigate the plasticization of cellulose triacetate films is demonstrated.Mekhanika Polimerov, Vol. 4, No. 3, pp. 555–558, 1968  相似文献

The enthalpies of vaporization of different classes of phosphorylated alcohols and amines were determined from their enthalpies of solution in hexane and carbon tetrachloride. The enthalpies of specific (hydrogen-bond) interaction with the solvents (chloroform and pyridine) of derivatives containing X-H groups (X=O or N) in the α-position to the P=O group were determined. The results were explained in terms of the spatial structure of such compounds. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献
