would be detectable by surface decoration. On the other hand, slow crystallization as takes place at 77-78 "C might produce the highly regular folding, which is the possible cause for the high dissolution temperature of crystals grown in this temperature range. This issue is currently receiving further attention. At this point an important general issue arises about crystal dissolution temperatures: namely, its concentration dependence. It has become customary to quote a single Tdvalue when referring to dilute polymer solutions (
