摘　　要：试验采用电子转移再生催化剂原子转移自由基聚合(ARGET-ATRP)技术,制备了一系列不同相对分子质量和阳离子化度的季铵型阳离子聚电解质Q-PDE。在探讨QPDE水溶液性质的基础上,分析改性剂相对分子质量和阳离子化度对棉织物无盐染色性能的影响。结果表明,改性后棉织物的活性染料无盐染色性能提高,匀染性和色牢度优良。Quaternized cationic polyelectrolytes Q-PDE with varied molecular mass and cationic degree are synthesized by atom transfer radical polymerization with activator regenerated by electron transfer （ARGET-ATRP） technology. Based on the investigation of Q-PDE solution behavior, the effects of molecular mass and cationic degree on salt-free reactive dyeing performance of treated cotton fabric are investigated. The results demonstrate that the salt-free reactive dyeing performance of cotton fabric after modification is improved. The levelness and color fastness of dyed cotton fabric are good.
