โœฆ Synopsis

The sol-gel transition of atactic polystyrene in carbon disulfide has been studied using neutron scattering. The measurements were performed in classical and selective experimental conditions.

All data are taken in the concentration regime from dilute to semidilute over a wide temperature range from 170 to 300 K. Based on the results obtained, the molecular mechanism on the sol-gel transition of the present system is discussed.

The sol-gel-glass transition of atactic polystyrene in carbon disulfide over a wide temperature range from 170 to 300 K has been investigated by neutron quasielastic scattering methods. A drastic narrowing of the quasielastic peaks was observed for the present system as the temperature is lowered a

The sol-gel transition of the system tetramethylorthosilicate-water-methanol under basic conditions has been studied by rheological measurements. The gelation time t(g) has been determined from the measurements of the elastic G' and viscous G'' moduli as a function of time at different frequencies a
