摘要
采用半预聚法合成了聚醚型聚氨酯弹性体;分别对预聚反应的时间、温度进行了考查,确定了合适的反应条件;并对影响弹性体性能的几种因素:水分的含量、软硬段比例、NCO/OH、聚醚的分子质量以及后熟化时间等进行了研究。
The polyether-based polyurethane elastomers were synthesized by quasi-prepolymer method. The time and temperature of prepolymerization reaction were examined and the appropriate reaction qualification were ascertained ; The effects of moisture content, the mass ratio of hard segment and soft segment, molecular weight of polyethylene glycol, post ageing time on polyurethane elastomers performances were particularly discussed.
