dc.description.abstract	Dynamic light scattering studies have been carried on (1) chemically cross-linked polyacrylamide (CCPA) gel (2) photopolymerized polyacrylamide (PPPA) gel and (3) PPPA gel with 93nm diameter polystyrene particles incorporated. All the three gels exhibited nonergodicity. The diffusion coefficients have been obtained by analyzing the initial time decay of intermediate scattering functions (ISF) for all the three gels. ISFs obtained for different scattering wave-vectors for pure gels showed collapse, whereas such a collapse was not observed for gel with particles, which imply a change in dynamics with incorporation of particles. The results are understood based on models that describe dynamics in gels. © 2006 American Institute of Physics.
