| Abstract: | Polymerization of low molecular weight cyclic ethers was investigated under pulsed plasma conditions. Film formation conditions were adjusted to optimize retention of ethylene oxide (EO) content of the monomers in the resultant plasma generated polymers. To a large extent this goal was achieved with the 12-crown-4 and 15-crown-5 monomers, but not with dioxane. Films obtained from the 12-crown-4 monomer under ultra low power inputs are shown to be highly resistant to protein adsorption, while exhibiting good chemical compositional stability and adhesion during prolonged immersion in aqueous solutions. The dramatic differences observed in contrasting polymer film compositions from 12-crown-4 and dioxane are believed to arise from distinctive differences in the low electron impact fragmentation patterns of these two compounds, as discussed in this report. |
