摘要
合成了N-丙烯酰-N’-肉桂哌嗪(ACP)与丙烯酸(AA)的共聚物聚(N-丙烯酰-N’-肉桂哌嗪-共聚-丙烯酸)(P(ACP-co-AA))。紫外吸收和傅里叶红外光谱跟踪结果表明:ACP及其共聚物P(ACP-co-AA)分别具有较好的光敏性和光交联性。在光照约30 min后,不同组成共聚物膜的光交联基本完成,交联膜在酸、碱水溶液中均可溶胀,在碱性中的溶胀率比在酸性中的溶胀率要大,pH为6-7时其溶胀率最小,表现出明显的pH敏感性。随光照时间的延长,肉桂基含量较高的共聚物交联膜在pH为9的溶液中的瞬间最大溶胀率出现较早,肉桂基含量较低的则较晚。
A new photo-monomer, N-acryl-N＇-cinnarnenylpiperazine （ACP）, and its copolymers with acrylic acid （P（ACP-co-AA）） have been synthesized. The UV and FT-IR speclra showed that P（ACP-co-AA） have better photosensitivity and photocrosslinking properties. The swelling ratio （SR） of the photocrosslinking films of the P（ACP-co-AA） copolymers with different compositions is higher in the alkaline solution than in the acidic solution. The lowest SR occurred at pH=6~7, showing obvious pH-sensitivity. At pH=9, the instantaneous maximum SR of the copolymers with a higher content of cinnamenyl groups appeared earlier with prolonged irradiation time.
