In an effort to gain information on the gelation mechanism of poly(vinyl chloride) (PVC) in diethyl malonate, investigations of dilute PVC solutions were made using transient electric birefringence, flow birefringence, dynamic light scattering and viscometry. The dynamical structure factor obtained from the cumulant analysis of the autocorrelation function of scattered field exhibits an anomalous K dependence which can be attributed to an intramolecular effect. Measurements of intrinsic viscosity and rotational diffusion coefficient provide information on the internal structure of the aggregates formed by quenching dilute PVC solutions.
