✦ Synopsis
Molecular modelling studies have been undertaken to investigate the properties of poly(methylidene malonate 2.1.2). The in¯uence of several factors has been evaluated: the size effect with three degrees of polymerization (n = 5, 20 and 40), the role of the solvent (polar and apolar) with an implicit solvation treatment, the in¯uence of the degree of erosion, and the role of the tacticity. Estimations of the lipophilicity of oligomers have been obtained by Monte Carlo studies followed by molecular lipophilic potential calculations on the molecular surfaces of the conformers. Then, using molecular dynamics with an implicit treatment of solvent, the shape of the polymers was studied. The results are in good agreement with experimental solubility information and new data about the potential role of the tacticity have been obtained.
