Abstract

Self-etching primers and adhesives contain very hydrophilic acidic monomers that result in high water sorption/solubilities of their polymers. However, the chemical composition of these products varies widely. The purpose of this work was to vary the chemical composition of experimental self-etching primers and adhesives to determine if the water sorption/solubility of the polymers were affected in a predictable manner. The Hoy's solubility parameters of these mixtures were calculated to permit ranking of the degree of hydrophilicity of the polymers. Water sorption/solubility was measured according to ISO 4049. The results showed highly significant (R² = 0.86, P < 0.001) correlations between water sorption and Hoy's solubility parameter for polar forces (δ_p) of the polymers. Similar correlations were obtained between polymer solubility and δ_p. When these results were compared with previously published results obtained with more hydrophobic resins, excellent correlations were obtained, indicating that Hoy's δ_p values may be used to predict the water sorption behavior of methylmethacrylate polymers.
