| Abstract: | Adopting a weak polarity non -toxic organic matter of toluene as solvent, unsaturated ternary copolymerization chlorohydrin rubber is prepared by precipitation polymerization. The experimental results show that the proper reaction conditions as follows： reaction temperature 70 ℃, reaction time 6 hours, the optimal solvent for n-hexane. The volume ration of epoxy chloropropane, epoxy ethane, allyl glycidyl ether and catalyst is 70 ： 9 ： 3 3： 3. Among them the volume ratio of catalyst for triisobutylaluminium, phosphate and N, N- dimethyl aniline is 100 ： 160 ： 12. Unsaturated ternary copolymerization chlorohydrin rubber is characterized by respectively using the fourier transform infrared spectrum, thermal analysis and mechanical property determination methods. |
