Abstract

A flame retardant resin composition is herein disclosed which comprises (a) an SPS, (b) a thermoplastic resin having a reactive polar group, (c) a compatibilizing agent having compatibility with the component (a) and a polar group capable of reacting with the component (b), (d) a flame retardant and (e) a flame retardant auxiliary, a weight ratio of the component (a)/the component (b) being less than 1.5, the amount of the component (c) being in the range of 0.5 to 10% by weight with respect to 100% by weight of the total of the components (a), (b) and (c), the amount of the component (d) being 10 parts by weight or more and the amount of the component (e) being 3 parts by weight or more with respect to 100 parts by weight of the total of the components (a), (b) and (c). According to the present invention, there can be provided the resin composition maintaining the excellent characteristics of an SPS-polyamide alloy and having a high flame retardancy.

Claims

exact text as granted — not AI-modified
1 . A flame retardant resin composition which comprises (a) a styrenic polymer having a syndiotactic configuration, (b) a thermoplastic resin having a reactive polar group, (c) a compatibilizing agent having compatibility with the component (a) and a polar group capable of reacting with the component (b), (d) a flame retardant and (e) a flame retardant auxiliary, a weight ratio of the component (a)/the component (b) being less than 1.5, the amount of the component (c) being in the range of 0.5 to 10% by weight with respect to 100% by weight of the total of the components (a), (b) and (c), the amount of the component (d) being 10 parts by weight or more and the amount of the component (e) being 3 parts by weight or more with respect to 100 parts by weight of the total of the components (a), (b) and (c).  
     
     
         2 . The flame retardant resin composition according to  claim 1  wherein the component (d) is a brominated polystyrene, and a weight ratio of the component (c)/[the component (a)+ the component (c)] is more than 0.06.  
     
     
         3 . The flame retardant resin composition according to  claim 1  wherein the component (d) is poly(dibromophenylene oxide), and a weight ratio of the component (c)/[the component (a)+the component (c)] is less than 0.06.  
     
     
         4 . The flame retardant resin composition according to  claim 1  wherein the component (b) is a polyamide.
