Determination of pre-gelation and post-gelation activation energies during free radical crosslinking copolymerization
(Taylor & Francis Ltd, 2005)
Steady-state fluorescence (SSF) and dilatoraetric techniques were used to study the free-radical crosslinking copolymerization (FCC) of styrene (S) and divinylbenzene (DVB) in bulk. The gel points (t g) were recorded by ...
Dissolution of Al2O3-polystyrene latex composites: A fluorescence study
(Taylor & Francis Ltd, 2005)
This work reports the use of the steady state fluorescence (SSF) technique to study dissolution of a composite film formed from a mixture of Al 2O3 and polystyrene (PS) latex particles. The composite films were cast from ...
Comparision of critical parameters of polymerization and gelation processes: A fast transient fluorescence study
(World Scientific Publ Co Pte Ltd, 2005-03-10)
The fast transient fluorescence technique was used to study free-radical polymerization and crosslinking copolymerization of styrene. Ethylene glycol dimethacrylate and Pyrene were used as crosslinking agent and fluorescence ...
Synthesis and liquid crystalline behavior of random copolymer of poly(ethylene oxide) macromonomer and liquid crystalline monomer by the photon transmission technique
(Taylor & Francis Inc, 2005-12)
Random copolymers of poly(ethylene oxide) macromonomer with p-vinylbenzyl end-functional group (PEOVB) and liquid crystalline monomer, namely 6-(4-cyanobiphenyl-4'-oxy)hexyl acrylate (COA), were prepared by conventional ...
The liquid–glass transition – is it a fourth order phase transition?
(Elsevier Science, 2005-09-01)
The liquid-glass transition is analyzed using a theory of Brownian motion in liquids recently developed by the author. It is shown that if a liquid could be cooled in quasi-static process and still avoids crystallization ...
Small molecule desorption from a swelling polymeric glass in polymer solution: Energy transfer method
(Elsevier Science Sa, 2005-07-15)
Direct energy transfer (DET) method conjunction with fast transient fluorescence (FTRF) technique were used to study small molecule desorption from a swelling poly(methyl methacrylate) (PMMA) glass in polymer solution, ...
Universal behaviour of glass transition exponents in various polymeric systems
(VSP BV, Brill Academic Publishers, 2005)
The fast transient fluorescence (FTRF) technique was used to study the critical exponents during glass transition in free-radical cross-linking copolymerization (FCC). Methyl methacrylate (MMA), ethyl methacrylate (EMA) ...
Molecular recognition during sol-gel and gel-sol transition of kappa-iota carrageenan mixtures
(Taylor & Francis ltd, 2005-12)
Sol-gel and gel-sol phase transitions of kappa-iota (kappa-iota) carrageenan mixtures in two types of salts were studied using photon transmission technique. Here, KCl and CaCl2 were chosen as the proper salts for the ...
Percolation approach to film formation from surfactant-free polystyrene particles
(Taylor & Francis, 2005-09)
In this study, a film formation process from surfactant-free polystyrene (PS) latex particles is reported. Steady state fluorescence (SSF) and photon transmission (UVV) techniques were used to study the evolution of film ...
Film formation from nano-sized polystyrene latex particles
(John Wiley & Sons Ltd, 2005-05)
This work reports on the steady state fluorescence (SSF) technique for studying film formation from surfactant-free, nano-sized polystyrene (PS) latex particles prepared via emulsion polymerization. The latex films were ...
