THERMAL BEHAVIOR OF THERMOTROPIC HYDROXYETHYL CELLULOSE ACETATE/POLYETHYLENE BLENDS
<正> The thermal behavior of thermotropic hydroxythyl cellulose acetate (HECA)/polyethy-lene (PE) blends has been studied by DSC. It is found that the blends of HECA and PEare immiscible but the crystallization of PE is affected by HECA chains in the blends withmore than 50% HECA
which results in the subordinate crystallization of PE and the for-mation of imperfect structures in the PE crystals. The imperfection of PE crystals in theblends can be eliminated after annealing at 393K.
