摘　　要：本论文叙述了用聚氨酯对酪素进行接枝改性的研究。采用正交试验法研究了各反应因素对接枝共聚反应的影响，找出了较为理想的合成工艺。测定了接枝效率，并用红外光谱验证了反应的发生，浅析了反应机理。以酪素，及其改性产品进行了对比涂饰试验，结果表明该改性酪素产品既保持了天然酪素涂饰的优点，又在一定程度上改进了其耐湿擦牢度和耐曲挠性。In this paper described studies of modified casein with polyurethancs,influence of reaction factors on the graft copolymerization researched by orthogonal test,suitable synthetic technology of the graft copolymerization and determined grafting efficiency.The proof of grafting were established by IR spectrogram,the principal of reaction were explaned simply. Casein and modified casein used for finish tests on the leather, the results show,modified casein can keep the advantages of casein finish and improve the wet rub fastness,flexing resistance in a certain extent.
