N2 - 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 (δp) of the polymers. Similar correlations were obtained between polymer solubility and δp. When these results were compared with previously published results obtained with more hydrophobic resins, excellent correlations were obtained, indicating that Hoy's δp values may be used to predict the water sorption behavior of methylmethacrylate polymers.
