| 中文摘要: |
| 采用多面体低聚倍半硅氧烷(POSS)对聚氨酯（PU）进行改性，并对改性PU的性能进行研究。结果表明：采用超声波分散法可将POSS均匀分散在PU基体中；八乙烯基POSS对PU具有较好的补强和增韧作用，而八苯基POSS对PU的补强作用不明显。 |
| 英文摘要: |
| 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. |
