An acrylamide derivative of the following general formula (I) is used to prepare a polymer or copolymer:
wherein R1 represents a hydrogen atom, a straight-chain or branched alkyl group containing 1 to 4 carbon atoms or a C3-6 cycloalkyl group, R2 and R3 each independently represent an alkylene group containing 1 to 6 carbon atoms or R2 and R3 may be combined to form a ring, X represents a hydrogen atom, an amino group, a hydroxyl group, a halogen atom, a carboxyl group or a —COOR4 group wherein R4 represents a C1-6 straight-chain or branched alkyl, C3-6 cycloalkyl, phenyl, substituted phenyl, benzyl or substituted benzyl group, and Y represents an amino group, a halogen atom, a carboxyl group or a —COOR4 group wherein R4 represents a C1-6 straight-chain or branched alkyl, C3-6 cycloalkyl, phenyl, substituted phenyl, benzyl or substituted benzyl group. The thus obtained polymer or copolymer is a polymer or hydrogel incorporating many functional groups while maintaining the sensitive temperature response.
以下通式(I)的丙烯酰胺衍生物用于制备聚合物或共聚物:
其中R1代表氢原子,含有1至4个碳原子的直链或支链烷基或C3-6环烷基,R2和R3各自独立地代表含有1至6个碳原子的烷基或R2和R3可以结合形成环,X代表氢原子,氨基,羟基,卤素原子,羧基或—COOR4基团,其中R4代表C1-6直链或支链烷基,C3-6环烷基,苯基,取代苯基,苄基或取代苄基基团,而Y代表氨基,卤素原子,羧基或—COOR4基团,其中R4代表C1-6直链或支链烷基,C3-6环烷基,苯基,取代苯基,苄基或取代苄基基团。因此得到的聚合物或共聚物是一种聚合物或水凝胶,它包含许多功能基团,同时保持敏感的温度响应。
