摘要
Various compositions of cross-linked NR containing different amounts of a linear crystallizable hydrocarbon were studied. At a given content of hydrocarbon in the composition, the corresponding cooling thermograms show two peaks associated with the crystallization of the solvent. Different rates of solvent microsyneresis and crystallization, as well as the dependence of these rates on the solvent concentration in polymer bulk, lead to the appearance of one or two peaks of solvent crystallization in the corresponding cooling thermograms.
