【Abstract】 s Bromic flame retardant,Sb 2O 3,as well as free radical initiator and carburant,were used to prepare a flame retardant system for PS,and the flame retardance was studied.The experiment results showed that the addition of free radical initiator sharply reduced the content of bromine and cost,the transparence was improved as well.While the addition of carburant had good effect on the flame retardance and lessened drippage.更多还原
