Polyamino amphiphilic polymer could capture formaldehyde that was released gradually by fur. The polymer was synthesized by monomers with acylamide groups and vinyl polymer groups under certain condition and then Hofmann degradation.

• 通过含酰胺基单体和乙烯基类单体在一定条件下共聚合,经Hofmann降解,合成一种多氨基两亲性共聚物,用该共聚物处理甲醛鞣毛皮,使其长期固定在毛皮产品中,捕获在穿用过程中释放出的甲醛。
