  abstract = {To clarify the effect of the type of acrylic monomer and the molecular weight (Mn) of polydimethylsiloxane ({PDMS}) on the relationship among the internal structure, oxygen permeability coefficient [P(O2)] and transparency, crosslinked copolymers were prepared with two different acrylic monomers : methyl methacrylate ({MMA}) and trifluoroethyl methacrylate ({TFEMA}). {PDMS} macromers with Mn of 1700, 3300, 4700, and 7800 g/mol were used. {DSC} measurements suggested that all constituent phases were insoluble with each other. The Mn of {PDMS} affected both the light transmittance and P(O2). The relationship between the Mn and P(O2) over the low Mn range (1700 and 3300 g/mol), and the calculated {PDMS} domain size ratio, were found to support the [Mn]2/3 rule into the crosslinked copolymer. Furthermore, a 3300 g/mol Mn copolymer became transparent when the amount of {PDMS} was greater than {PMMA}. In addition, copolymerization with {TFEMA} drastically affected those properties, and this effect was much greater than the effect of the {PDMS} Mn. To clarify the mechanism of P(O2) improvement induced by {TFEMA} copolymerization, calculations on the relationship among the P(O2), {PDMS} volume fraction, and morphology model were performed, and some properties such as solubility parameters should play important roles.
