The Hildebrand solubility parameter (δ) provides a numerical estimate of the degree of interaction between materials and can be a good indication of solubility, particularly for nonpolar materials such as many polymers. Materials with similar values of δ are likely to be miscible. See more The Hildebrand solubility parameter is the square root of the cohesive energy density: $${\displaystyle \delta ={\sqrt {\frac {\Delta H_{v}-RT}{V_{m}}}}.}$$ The cohesive energy density is the amount of See more From the table, poly(ethylene) has a solubility parameter of 7.9 cal cm .
