The Relationship between the Change in Dynamic Viscoelasticity by Heat Treatment and Heat Resistance in Polystyrene Moldings

The mechanism of heat resistance improvement of polystyrene injection moldings by heat treatment was studied. The increase in the Heat Distortion Temperature（HDT） by heat treatment was confirmed. Meanwhile, in dynamic viscoelasticity measurement, the shoulder of the loss tangent（tanδ） appeared at 60...
