Comparison of gel swelling under organic vapor and in organic solvent
Erdoğan, Matem; Pekcan, Önder (Photoenergy Center Ain Shams Univ, 2005)A Fast Transient Fluorescence Technique (FTRF) was employed for studying swelling of disc shaped poly (methyl methacrylate) (PMMA) gels, which were prepared by free radical copolymerization of methyl (methacrylate) (MMA) ... -
Drying process in vapor swollen heterogels
Erdoğan, Matem; Pekcan, Önder (Springer, 2010)Disk-shaped heterogels were prepared by combining methyl methacrylate (MMA) and styrene (S) with ethylene glycol dimethacrylate (EGDM) as a crosslinker agent in the presence of 2,2'-azobisisobutyronitrile (AIBN). Swelling ... -
Fast transient fluorescence method for measuring swelling and drying activation energies of a polystyrene gel
Erdoğan, Matem; Pekcan, Önder (Elsevier Science Bv, 2004)The time-resolved, fast transient fluorescence (TRF) technique which uses a strobe master system (SMS), was employed for studying swelling and drying of disc-shaped polystyrene gels. Disc-shaped gels were prepared by ... -
Fast transient fluorescence technique for studying homopolymer mobility in a swelling gel
Erdoğan, Matem; Pekcan, Önder; Yağcı, Yusuf (2004)The mobility of pyrene end-capped polystyrene (Py-PSt) trapped in swollen polystyrene gels (PSt) was investigated. PSt gels were prepared by free radical cross-linking copolymerization (FCC) of styrene (St) and ethylene ... -
Molecular alignment during gel formation from methyl methacrylate: An excimer fluorescence study
Kaya, Demet; Erdoğan, Matem; Pekcan, Önder (Taylor & Francis Ltd, 2005)Glass transition during bulk polymerization was studied in free-radical cross-linking copolymerization (FCC) of methyl methacrylate (MMA) using the steady-state fluorescence (SSF) technique. Naphthalene (N) was used as a ... -
Reordering of polystyrene gel due to multiple swelling in organic vapor - Fast transient fluorescence technique study
Erdoğan, Matem; Pekcan, Önder (Elsevier Science Sa, 2006)Reordering of disc-shaped polystyrene (PS) gels due to multiple swelling, under organic vapor was studied by using Fast Transient Fluorescence (FTRF) technique. Disc-sbaped polystyrene gels were prepared by free radical ... -
Slow release of trapped homopolymers from a swelling polymeric gel: A fluorescence study
Erdoğan, Matem; Yağcı, Yusuf; Pekcan, Önder (Taylor & Francis Inc, 2008)In-situ steady-state fluorescence experiments were performed for studying slow release of pyrene-labeled polystyrene chains from polystyrene gels formed by free-radical crosslinking copolymerization. Atom transfer radical ...
