Abstract
The authors have studied the kinetics of "bleeding" during the heating of oriented and non-oriented plexiglas with accrued operating times of up to 16,000 h. They show that bleeding of the products of degradation of macromolecules from plexiglas is accompanied by a decrease in the volume of the polymer, which causes tensile stresses in the surface layers and may lead to surface cracking.
