Preserved Fulltext
Synthesis of phosphorus-containing polyurethane elastomers (PPUEs): Polyester diol was heated to 110-120 ºC, stirred and vacuumed for 2 h to remove trace water. When the temperature was reduced to 70 ºC, TDI was added and reacted for 2 h. The prepolymer was prepared. The molten chain extender and prepolymer were mixed and stirred fully. Then the mixture was put into a Teflon mould at 75 ºC for 2 h and 115 ºC for another 2 h. Finally, the PPUEs
