説明

Interactions between polystyrene and fillers having common benzyl group, e.g., styrene-grafted cellulose and partially benzylated cellulose, have been studied and the results were compared with those of cellulose filler.<BR>To this end the rheological characteristics of the melt in capillary flow and the mechanical properties of the molded sheet were determined with the following results.<BR>1) The melt containing filler showed higher plastic viscosity and lower Barus effect with increasing content of styrene-grafted cellulose, as in the case of cellulose, but it was scarecely affected by the partially benzylated cellulose.<BR>2) Filling with the partially benzylated cellulose improved the mechanical properties of the general purpose polystyrene sheet.<BR>3) The filler covered with many short benzyl groups seems to be more effective to polystyrene than that grafted with a few long polystyrene chains.grafted with a few long polystyrene chains.
