Notes:
The effects of thermal treatment in the 70-90°C. region on polybutene-1 crystals, prepared by precipitation from dilute pentyl acetate solutions and with lath, hexagonal, and square morphologies, have been studied by using electron microscopy. The stability of polybutene-1 crystals to thermal treatment increases in the order: lath 〈 hexagonal 〈 square. Elucidation of the crystallographic directions in unheated lath crystals with respect to the overall morphology was carried out; evidence for restricted folding in these crystals is discussed.
