The microgelation phenomenon during the curing of unsaturated polyester resin was investigated by both static and dynamic light scattering before gelation. The results of static light scattering revealed that the polymer molecular weight increased with degree of curing. The second virial coefficient

Static light scattering measurements were performed on dilute solutions of monodisperse poly(ethy1ene oxide) (PEO) in methanol at 25ยฐC. PEOs of five different molecular weights ranging from nominal M , = 8.6 X lo4 to 9.13 X lo5 were used. Linear Zimm plots were obtained for all the PEO samples: no d
Dynamic light scattering behaviour in the form of periodic oscillating correlation functions has been found from measurements on both physically and chemically crosslinked hydrogels. The former were aqueous methyl cellulose at the thermal gelation temperature and the latter were poly(N,Ndimethylacry
## Background: The differential light-scattering pattern, an indicatrix, provides the most complete characterization of the optical properties of a particle. Particle classification can be performed on the basis of particle parameters retrieved from the indicatrices. This classification extends th
