Fraction of Free Volume in Defective Structures of Butadiene and Acrylonitrile Copolymers and Absorption of Low Molecular Compounds

Fraction of Free Volume in Defective Structures of Butadiene and Acrylonitrile Copolymers and Absorption of Low Molecular Compounds

The correlation between the amount of sorbed solvents of different polarities, structures, and specific molar volumes ( n -heptane, methyl acetate, and toluene) in crosslinked butadiene-nitrile elastomers in terms of equilibrium swelling and the value of free volume in their defective structures is...

Description
Summary:The correlation between the amount of sorbed solvents of different polarities, structures, and specific molar volumes ( n -heptane, methyl acetate, and toluene) in crosslinked butadiene-nitrile elastomers in terms of equilibrium swelling and the value of free volume in their defective structures is established in this study by analogy with the dependence of the rotational mobility of nitroxyl radicals.
