Abstract: In this paper,a time-resolved small angle laser light scattering(SALS)apparatus has been described.In this apparatus,a two-dimensional CCDcamera has been used as a detector, then the intensity of the scattered light is converted to the digital signals and stored in the computer or in a video recorder for further data analysis.As a demonstration, the SALSpattern of polypropylene spherulite has been recorded and the data are presented in ways of grayed picture,three-demensional stack plot and contour plot.To show the feasibility of studying the dynamics of phase separation,the time evolution of light scattering during the cure-induced spinodial deconposition of an epoxy composite has been recorded.

Key words: Time-resolved light scattering, Dynamics of phase separation, Light scattering of spherulite, Epoxy resin
