The TEM images clearly show that there exist smudged polymer layer on the particle surface, and the thickness of the imprinting polymer layer is estimated to be about 20~30 nm with a relatively narrow size distribution, the polymer layer should be the product of SiO2 layer formed by TEOS and co-polymerization of functional monomer 4-Vpy and cross-linking agent EGDMA [19].
MIP against Phe was prepared by UV polymerization method using Phe as template molecule, MAA as a functional monomer and EGDMA as a crosslinker in the presence of five different porogenic solvents.
Of the polymers prepared with hydrophilic comonomers, only those containing NVP demonstrated sol contents that were similar to those of the PDMDPS; the sol contents of polymers containing EGDMA and AA were about 45 and 57%, respectively.
The higher number of the alkyl groups in the structure of BDMA than the number of alkyl groups in the structure of EGDMA stiffens the structure and [T.
The stretching vibration peak of saturated C-H at 2935 cm-1 may be attributed to the propyl of KH-550 and the methyl of MAA and EGDMA [25].
EGDMA and benzoyl peroxide were obtained from Sigma-Aldrich UK and Flurbiprofen was received as a kind gift from Global Pharmaceuticals Pvt.
In our work, porous terpolymers consisting of GMA, EGDMA, HEMA, and magnetic terpolymer were synthesized in the presence of butyl acetate, n-octyl alcohol, PVP K90, and PVA by suspension polymerization.
In the present work, it has been observed that the sample having a relatively high amount of EGDMA shows greater milkiness and lower transparency, a situation which may be attributed to the light scattering phenomena.

2-(dimethylamino) ethyl methacrylate, EGDMA, and potassium persulfate (KPS) were from Aldrich ([greater than or equal to] 99%); DMAEMA was distilled under reduced pressure.
In the past, trends have shown that by increasing the levels of standard acrylic coagents (TMPTMA, EGDMA, etc.
