When high density polyethylene is stretched, it noticeably whitens in the deformed region, indicating an increase in turbidity. To quantify the whitening of semicrystalline polymers during in situ drawing, a new technique based on incoherent polarized light scattering is presented, elucidating what happens in the microstructure. It can be applied to solid or liquid systems when changes in turbidity occur by some internal processes at the microscale. This low-cost technique provides the same type of results as those obtained using synchrotron X-ray microtomography.
