POLYSTYRENE COMPOSITION HAVING RESISTANCE TO THERMAL DECOMPOSITION

摘要

PURPOSE:To provide the title compsn. which has excellent thermal stability and scarcely emits decomposition gas, by adding a polyarylene sulfide and/or a polyarylene sulfone to a PS polymer. CONSTITUTION:0.01pt.wt. polyarylene sulfide (e.g., poly-p-phenylene suflide) and/or polyarylene sulfone (A) is added to 100pts.wt. PS polymer (B).
