| Abstract: | The polymer polyether polyol （POP） was synthesized using radiation synthesis method. The effect of isopropyl alcohol as chain transfer agent on viscosity, the solid content and thermal properties of the polymer poly- ether polyol was studied. When the content of c, hain transfer agent was higher than 0.6% , the solid content of poly- mer polyol was rapidly increased and the viscosity was slowly increased with the content of chain transfer agent in- creasing. The thermal gravimetric analysis showed that the thermal stability of polymer polyether polyol was changed with the different content of chain transfer agent. When the content of chain transfer agent was 0.8%, the thermal stability of POP particles was the best. |
| Keywords: | polymer polyether polyol chain transfer agent solid content viscosity |
