中文摘要:聚氨酯弹性体是由聚醚或聚酯柔性链段和含氨基甲酸酯基、脲基等极性基团的硬性链段所构成的嵌段聚合物。详细介绍了聚氨酯弹性体的结构特性和着色机理,包括染料母体与弹性基体的接枝或共聚、基体改性、着色工艺改进、新型分散染料设计与合成等。
外文摘要:Polyurethane elastomer is composed of polyether/polyester soft segments and hard segments which are made up of some polar group like urethane and urea.The structural characteristics and coloring mechanism of polyurethane elastomer are introduced in detail,including the grafting or copolymerization of dye chromophore and elastic matrix,matrix modification,improvement of coloring process,design and synthesis of new disperse dyes,etc.
