4、Effect of End- closing Rate on performance of PTMG Polyurethane Plastic Adhesive
8、A series of polyurethane (PU) elastomer were synthesized from polyester(PEA, PEPA) or polyether(PTMG), toluene dissocyanate (TDI), mixture of triisopropanolamine(TIPA) and 1,4-butanediol(BDO).
2、Polyoxytertramethylene (PTMG) is synthetized in one step using heteropoly acid as catalyst. We discussed the factors which influenced the yield of PTMG.
7、Medical thermoplastic polyether urethanes(TPU) based on MDI/PTMG/BDO system were prepared by one -shot, prepolymer and semi-prepolymer processes with equivalent stoichiometries respectively.
3、Study on Preparation and Properies of a New PTMG-PO Copolymer Polyurethane Elastomers
10、以聚酯（PEA、PEPA）或聚醚（PTMG）和TDI为原料合成聚氨酯预聚体，用三异*醇* （TIPA）和1，4-丁二醇（BDO）的混合物作扩链剂制备聚氨酯**体。
9、介绍了四*呋喃聚醚(PTMG)聚氨酯**体的*能。讨论了其化学结构对PU**体环境*能的影响。
1、Study on Mechanical Properties of MDI/PTMG Type Polyurethane Elastomer
6、The properties of PTMG-PU were introduced in this paper, and the effects of the chemical structure on the PU elastomer properties were also discussed.
5、PTMG is widely used in the field of chemical industry, for example synthesis PU.
