| Abstract: |
| Polyurethane（PU） was modified by polyhedral oligomeric silsesquioxane(POSS),and the properties of modified PU were investigated.The results showed that，POSS was uniformly dispersed in PU matrix by using ultrasonic dispersion method；octavinylsilsesquioxane(OVS) possessed preferable reinforcing and toughening effects，but octaphenylsilsesquioxane(OPS) had no significant reinforcing effect. |
