The physical and thermal characterizations of films of poly(l-butene) (PB-1
) with an oligomer terpenic-based resin (Clearon P125), glassy at room temp
erature, were examined by optical microscopy, differential scanning calorim
etry (DSC), and differential mechanical thermal analysis (DMTA). The rheolo
gical behavior of the molten mixtures was also examined. The results indica
te that the Clearon P125 and PB-1 results in a one-phase system in the melt
.
