| titleOfInvention | Polyarylene sulfide sulfone/polyether sulfone copolymer and preparation method thereof |
| abstract | The invention discloses a polyarylene sulfide sulfone/polyether sulfone copolymer and a preparation method thereof, which is characterized in that by weight: 143.5-272.65 parts of 4,4'-dichlorodiphenyl sulfone, 65.00-123.5 parts of sodium sulfide Parts, 0.2~10 parts of sodium hydroxide, 0.5~20 parts of catalyst, 200~860 parts of solvent, put into the reactor, under the protection of nitrogen, dehydration reaction at 140~198 o C for 0.5~3h to generate polyarylene sulfide Prepolymer of sulfone, stored at 100~140 o C; 14.35~143.5 parts of 4,4'-dichlorodiphenyl sulfone, 5.5~176 parts of diphenol monomer, 7~100 parts of potassium carbonate, 40 parts of solvent ~600 parts, 26~100 parts of dehydrating agent, added to the reactor, under the protection of nitrogen, dehydration reaction at a temperature of 145~180 o C for 10~12h, forming a prepolymer of polyethersulfone, cooling to 90~160 o Store at C; mix the above polyarylene sulfide sulfone prepolymer with polyethersulfone prepolymer, heat to 140~200 o C for 4~12 hours, and then react at 166~230 o C for 3~8 hours to obtain poly Arylsulfidesulfone/polyethersulfone copolymer. |
