Phase separation Light scattering study

In order to shift to PMAA/water and PMAA/MAA/water systems, phase separation is effected by starting the system at a lower temperature, and then placing it at a higher temperature. This is because such a system has an LCST, instead of a UCST. We note the plots in Figs. 1.1.5-1.1.7, which show points that were subject to light scattering studies. [Pg.69]

Light scattering and electron microscopy studies of aqueous PVME solutions and PVME microgels were carried out by Arndt et al. [329,330]. They noted that the Mw of PVME in water was always higher (up to 20 times) than its value (Mw = 46 000gmoH) determined in organic solvent (butanone), even for dilute aqueous PVME solutions well below the phase-separation temperature [330]. Moreover the molar masses of the polymer in water depended on solution preparation conditions. The authors concluded that PVME does not exist as isolated chains in water, but forms loose aggregates (Rh = 200-220 nm) which decrease in size as the solution temperature passes... [Pg.75]

The phase separation behavior during curing of polyetherimide (PEI) modified diglycidyl ether of bisphenol A (DGEBA) epoxy and PEI modified bisphenol A dicyanate (BPACY) were studied using SEM, light scattering, and dynamic mechanical analyzer. [Pg.108]
