The role of weak intermolecular interaction in the formation of associatedstructures in (meth)acrylates

The correlation of the chemical structure of(meth)acrylate molecules to som e physical properties of liquid media, including binary monomer solutions a nd solutions of monomers in their saturated counterparts, was studied by ES R spectroscopy (spin probe technique) and thermomechanics. By the character of a change in physical properties (structural transition temperatures in the monomers and binary solutions), the contributions of the double bond, t he alpha -methyl group, and the CH2 groups of the alkyl moiety to the forma tion of associated structures of liquid (meth)acrylates were determined. Th e obtained results were rationalized in terms of the model of reversible in termolecular pair interactions, attracting the concept of physical networks formed in the systems of interest.
