Title:
ポリビフェニールスルホンエーテル及びポリエーテルスルホンの共重合体の調製方法
Document Type and Number:
Japanese Patent JP2013508516
Kind Code:
A
Abstract:
A method for preparing terpolymer of poly (biphenyl sulfone ether) and poly (ether sulfone) comprises: adding high-temperature organic solvent into a flask, stirring and heating to 80°C, adding 4,4'-dichlorodiphenylsulfone,4,4'-Bis(4-chlorophenyl)sulionyl-1,1'-biphenyl and 4,4'-dihydroxydiphenylsulfone with solid content of 20-35%; stirring until monomers are completely dissolved, heating to 100°C, adding salt-forming agent and xylene; stirring while heating so that salt-forming reaction begins in the system, wherein the system temperature is controlled between 190°C and 210°C; when the amount of water discharged reaches the theoretical value, the first stage of salt-forming reaction is finished; heating the system to 230-236°C, and maintaining for 3-4 hours to obtain polymer viscous liquid; and refining the polymer viscous liquid to obtain a terpolymer containing different structural units in the molecular chain, wherein the Tg of the terpolymer, can be regulated by changing the ratio of the two dichloro-containing monomers.
