背景:聚氨酯易于加工、物理性能优良,广泛用于水声学。这类化合物通常由商品化的甲苯二异氰酸酯/聚四氢呋喃多元醇(TDI/PTMG)预聚体和扩链剂反应生成,得到的产品不一定具有最佳静态物理性能。
Background: Polyurethane is easy to process and has excellent physical properties and is widely used in water acoustics. Such compounds are usually formed by the reaction of a commercial TDI / polytetrahydrofuran polyol (TDI / PTMG) prepolymer with a chain extender and the resulting product may not necessarily have the best static physical properties.
