โฆ Synopsis
The nucleation behavior of a poly(ethy1ene oxide) melt is measured as the material crystallizes under defined conditions of shear and temperature. Polarized light microscopy is used as the measuring technique. A strong dependence of nucleation rate on supercooling and imposed stress was found. This behavior is explained in terms of stress-induced supercooling of melts. A correlation between the nucleation behavior and morphology of the sheared material is attempted.
