【 摘 要 】
Two novel polyurethane films were successfully synthesized. One was from hydroxylated tung oil (HTO) and polymethylene polyphenyl isocyanate (PAPI), which was designated as HTO-PAPI; and the other was from HTO end-capped a traditional polyurethane prepolymer and PAPI, which was designated as PP-HTO-PAPI. FTIR and NMR results show that the prepared HTO-PAPI and PP-HTO-PAPI are the expected structures. Mechanical testing result shows that the Young's modulus and elongation at break for HTO-PAPI and PP-HTO-PAPI are 282.13 MPa, 1.8 MPa and 14.15%, 218.23%, respectively, indicating that the two polyurethane films have very distinctive properties. And the properties can be controlled by incorporating different ratio of HTO and prepolymer. The present work provides a good foundation for the synthesis of novel polyurethane adhesives that will be hopefully used in different applications.
