## Abstract One of the most important features influencing the mechanical behavior of a fabricated thermoplastic item is the spatial arrangement of the polymer molecules. __Inter alia__ processes developed for controlling the pattern of orientation of the polymer molecules are discussed.
Melting of acrylonitrile polymers (which have a tendency to degrade before melting) was detected during their heat treatments at high heating rates (i.e., 80ยฐC min ฯช1 or above). The probable reason for their melting at such higher heating rates is discussed. The melting behavior of acrylonitrile pol
Specific heats for poly( methyl methacrylate), poly( diethylaminoethyl methacrylate), poly(cyclohexy1 methacrylate), poly(ally1 methacrylate), and poly(ethy1 acrylate) were measured from 120 to 300ยฐC. with a drop calorimeter. It was found that existing solidstate theories and equations were unable t
