FLAME-RETARDANT RESIN COMPOSITION

摘要

A flame-retardant resin composition comprising (a) SPS, (b) a thermoplastic resin having reactive polar groups, (c) a compatibilizer compatible with the component (a) and having a polar group reactive with the component (b), (d) a flame retardant and (e) an auxiliary flame retardant, wherein the (a) to (b) weight ratio is less than 1.5, the amount of the component (c) is 0.5 to 10 wt.% when the total of the components (a), (b) and (c) is taken as 100 wt. %, and the amounts of the components (d) and (e) are at least 10 pts. by wt. and at least 3 pts. by wt. respectively per 100 pts. by wt. of the total of the components (a), (b) and (c). A particular example of the above composition is an SPS/polyamide alloy composition exhibiting high flame retardance while retaining excellent characteristics inherent in SPS/polyamide alloy.
