Methods for producing a polyamide having an optical absorber pendent from the polyamide's backbone (OAMB-polyamide) may comprise: esterifying a hydroxyl-pendent optical absorber with a halogen-terminal aliphatic acid to yield a halogen-terminal alkyl-optical absorber; and N-alkylating a polyamide with the halogen-terminal alkyl-optical absorber to yield the OAMB-polyamide. Other methods for producing an OAMB-polyamide may comprise: esterifying a carboxyl-pendent optical absorber with a halogen-terminal aliphatic alcohol to yield a halogen-terminal alkyl-optical absorber; and N-alkylating a polyamide with the modified optical absorber to yield a polyamide having the OAMB-polyamide.
生产具有悬垂于聚酰胺骨架的光学吸收体的聚酰胺(OAMB-聚酰胺)的方法可包括:用卤素端脂肪族酸酯化悬垂于羟基的光学吸收体,得到卤素端烷基光学吸收体;用卤素端烷基光学吸收体对聚酰胺进行 N-烷基化,得到 OAMB-聚酰胺。生产 OAMB 聚酰胺的其他方法可包括:用卤素末端
脂肪醇酯化羧基末端光吸收剂,生成卤素末端烷基光吸收剂;用改性光吸收剂对聚酰胺进行 N-烷基化,生成具有 OAMB 聚酰胺的聚酰胺。
