摘　　要：研究了在聚醚多元醇用量不变的情况下 ,Rt 值 (即配方中NCO基团的物质的量与所有OH基团的物质的量的比值 )和COOH含量变化对乳液性能的影响。结果表明 ,Rt 值和COOH含量对乳液稳定性、胶膜的吸水率。The effects of R t value (the mol ratio of NCO group and all OH groups) and content of carboxyl on polyurethane emulsion were studied while the content of polyether glycol was fixed. The results showed that they had great effects on stability of polyurethane emulsion and water absorbed rate and mechanical properties of film.
