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 ...
Reversible film formation from PS doped PNIPAM particles in various compositions
(John Wiley & Sons Inc, 2008-02)
Film formation from polystyrene (PS) doped poly(N-isopropylacrylamide) (PNIPAM) particles was studied using photon transmission technique. The transmitted light intensity, Itr, was monitored during film formation process. ...
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 ...
Critical behavior of thermal phase transitions of iota-carrageenan in CaCl2 solution
(Elsevier B.V., 2006-07-15)
In situ photon transmission method was applied to study thermal phase transitions of ?-carrageenan in CaCl2 solution. Coil-to-helix (c-h) and helix-to-dimer (h-d) transitions were detected upon cooling. An extra dimer-to-dimer ...
