Beschreibung
Zusammenfassung:	The invention provides a process comprising reacting an epoxy novolac resin with monohydroxy aromatic compound, optionally in the presence of a poly-functional agent for linking together the epoxy novolac chains. The polymers thus obtained are modified, solid, novolac epoxy resins which are useful as stabilizers for flame retardants such as polystyrene-block- brominated polybutadiene-block-polystyrene. 本发明提供种方法，其包括：使线型酚醛环氧树脂与单羟基芳族化合物任选在多官能试剂的存在下反应，所述多官能试剂用于将所述线型酚醛环氧链连接在起。由此获得的聚合物是改性的固体线型酚醛环氧树脂，其用作阻燃剂例如聚苯乙烯-嵌段-溴化聚丁二烯-嵌段-聚苯乙烯的稳定剂。
