This study was conducted to investigate the effect of crosslink density, type and concentration of initiator, the use of a complex initiator system, porogen, and diluent on the most relevant parameters of FP, such as sustainability of the front, temperature profile, front velocity, and yield. The products were also characterized for intruded pore volume, pore-size distribution, epoxy-functionality number, and surface morphology. Higher crosslink densities (CLDs) and initiator concentration produced higher front velocities, whereas no trend in front temperature was noted. A complex initiation system was effective in stabilizing and increasing the polymerization yield. Relative to suspension polymerization (SP), FP products synthesized without a solvent were microporous, whereas micro-to-macroporous products were obtained in the presence of a solvent (for HEMA-EGDM polymers). We also present, explain, and discuss the exotic patterns observed under a microscope. We observed two basic types of spatial patterns, namely, planar and nonplanar patterns. The type of planar pattern observed under scanning electron microscopy (SEM) has a spatial impulse that appears as a loop followed by regular periodic motion in the radial and axial directions. This behavior gives rise to a repeating pattern that is a few microns thick. Also, nonplanar patterns, namely, layered concentric rings and winding staircase patterns, were observed under SEM.</p>10acopolymerization10apatterns10aPolymers10aporosity1 aPujari, Narahari, S.1 aInamdar, Satish, R.1 aAmbekar, Jalindar, D.1 aKulkarni, B., D.1 aPonrathnam, Surendra  uhttps://library.ncl.res.in/content/exhaustive-analysis-frontal-copolymerization-functionalized-monovinyl-and-divinyl-monomers-001741nas a2200241   4500008004100000022001400041245017200055210006900227260008600296300001200382490000700394520074800401653003701149653002701186653002101213653002301234653002201257653002301279100002701302700002501329700001901354856012601373       2016                        eng d  a1060-132500aSynthesis of 2-phenoxy-2-phenylethyl acrylate and copolymerization with 2-phenylethyl acrylate: estimation of monomer reactivity ratios, thermal and optical properties0 aSynthesis of 2phenoxy2phenylethyl acrylate and copolymerization   a530 WALNUT STREET, STE 850, PHILADELPHIA, PA 19106 USAbTAYLOR & FRANCIS INCcMAY  a457-4640 v533 a<p>A new aromatic based monomer 2-phenoxy-2-phenylethyl acrylate (PPEA) was synthesized. Copolymers of PPEA with 2-phenylethyl acrylate (PEA) were prepared by free radical polymerization. The reactivity ratios were estimated using various graphical methods. Structural parameters of the copolymers were obtained by calculating the dyad monomer sequence fractions and the mean sequence length. Optical properties of polymers such as refractive indices and UV-Visible absorption were investigated. The glass transition temperature and thermal degradation behavior of the copolymers were studied. Combined with the RI, transparency and thermal properties, prepared copolymers hold great promise as materials for intraocular lens applications.</p>10a2-Phenoxy-2-phenylethyl acrylate10a2-phenylethyl acrylate10acopolymerization10aOptical properties10areactivity ratios10aThermal properties1 aGhorpade, Ravindra, V.1 aPonrathnam, Surendra1 aChavan, Nayaku  uhttps://library.ncl.res.in/content/synthesis-2-phenoxy-2-phenylethyl-acrylate-and-copolymerization-2-phenylethyl-acrylate
