1344 Improvement of Impact Value of ABS Polymer prepared by Solvent Casting
Details
A room temperature solvent casting (RTSC) treatment, that is solidification after dissolving plastics into organic solvent, has been applied to bulk articled. The attractive points are not only the casting at room temperature, but also saving the production period and cost on molding of polymer. Thus, influences of acetone, one of typical solvent in environmental closed system, on mechanical properties of ABS polymer treated by RTSC-treatment have been studied. Although the RTSC-treatment softens the ABS polymer, it improves the Charpy impact value, which is 1.75 times larger than that before the RTSC-treatment. The improvement of impact value is mainly explained by residual mass of acetone in ABS polymer molecule.
