Abstract
The original optical method was used for the first time to obtain complete diagrams of the state of mixtures of low-density polyethylene with o-xylene and ethylbenzene. The diagrams are of the type describing the phase state of systems partially crystalline polymer–good solvent. In contrast to the diagrams described in the literature, the diagrams described here contain an additional boundary curve for the solubility of the liquid in the polymer. Using the coordinates of the intersection of this line with the curve of complete amorphization of the polymer, five alkyl benzenes were ranked according to their thermodynamic affinity to low-density polyethylene.
