Abstract Hydrophilic polymers were prepared by radiation cast-polymerization of methoxypolyethyleneglycole methacrylate monomers for biomedical applications, and the relationship between physical characterization and molecular structure was studied. As the number, n, of oxyethylene units, -(OCH2CH2) n -, in the monomers increased, the hydration ability of the polymers increased markedly until n = 4 and after that increased moderately. The mechanical properties, such as tensile and tear strength decreased, and the elongation at break increased to a maximum and then decreased with increasing n. This appeared to be a characteristic of the polymers of methoxypolyethyleneglycole methacrylate monomers. The mechanical properties of the copolymers resulting from the copolymerization of methoxypolyethyleneglycole methacrylate with hydroxyhexyl methacrylate monomer were also studied.
