接枝共聚技术提高ABS、SBS聚合物成炭率

Enhancement of Char Yield of ABS and SBS via Graft Copolymerization

通过接枝共聚提高高聚物的成炭率 ,是改善材料阻燃性的有效技术措施。将丙烯酸或甲基丙烯酸及它们的钠盐接枝到某些ABS和SBS上 ,可明显提高接枝共聚物的热稳定性、成炭率及阻燃性。

Enhancing char yield of ABS and SBS via graft copolymerization is one of the effective approaches to improve the flame retardancy of polymers. The thermal stability, char yield and flame retardancy have been obviously improved by grafting acrylic or methacrylic acid or their sodium salts into ABS or SBS.
