Table 2.

Formulations, and mean ± standard deviation (each n = 50) nodule and pore sizes for monoliths consisting of 1% DMPA initiator in a mixture of OMA, EDMA, 1-dodecanol, and cyclohexanol. Formulations also correspond to panel letters in Figure 2. Formulations A-F maintained a 1:1 OMA:EDMA ratio while varying the OMA+EDMA:porogen ratio. Formulations G-L maintained a 65% total porogen content while varying the OMA:EDMA ratio.
