Abstract: The characteristics of Rayleigh scattering of high density polyethylene in the presence of dibenzylidenesorbital as nucleation reagent was investigated and the existence of rodlike crystals was confirmed. The effect of nucleation reagent on the crystallization was discussed and the length and radius of rod crystal were calculated.

Key words: high density polyethylene, crystallization, dibenzylidenesorbital, Rayleigh scattering, nucleation reagent
