Abstract
The three polyols, poly(trimethylene ether) glycol 2000, poly(tetramethylene ether) glycol 2000 and poly (tetramethylene ether) glycol 1000 were reacted with 4,4-diphenylmethane diisocyanate to get polyurethanes. The synthesized three polyurethanes were measured by FT-IR, NMR for investigating chemical structures. Through two spectroscophical methods, It is found that urethane group exists in the three polymers. From the evaluation of hardness, glass transition temperature, tensile strength, and water resistance, the results showed increasing order of Poly(tetramethylene ether) glycol 1000 > Poly(trimethylene ether) glycol 2000 > Poly(tetramethylene ether) glycol 2000 with the content of hard segment in polyurethane.
