nPolyether-ether-ketone and polyethersulfone form weight percent and between 95-5: 5-95, adjust.
Description
The invention belongs to the technology of preparing of aromatic polyether-ether ketone copolymer.
Though polyether-ether-ketone excellent combination property.2 problems are anxious to be waited to improve but also find to have in it is used.The one, the processing temperature height needs 400 ℃ approximately, and the one, second-order transition temperature not high enough (143 ℃).In the last few years, employing was constantly delivered with the patent that the way of other engineering plastics blend is carried out modification, as European patent EP 157.4 66, EP176.988.Japanese Patent JP6210161 etc.
But these co-mixing systems, though processing temperature is made moderate progress, because of most systems and polyether-ether-ketone do not dissolve each other, so the second-order transition temperature of polyether-ether-ketone can not get improving.We are analyzing on the previous work basis, adopt the oligopolymer of polyethersulfone and the way of polyether ether ketone oligomer copolymerization to synthesize the polyether-ether-ketone segmented copolymer.The result shows, has finished the present invention thereby this multipolymer has the new capability that is different from above-mentioned blend.
The present invention synthesizes different polymerization degree X at first as required respectively
nPolyether-ether-ketone and polyethersulfone oligomer.Afterwards two kinds of oligopolymers are obtained needed multipolymer by mixing copolymerization in varing proportions.And the mean polymerisation degree X of oligopolymer
nBe according to following formula X
n=(1+r)/(1-r) control by two kinds of monomeric ratio of components r, to polyether-ether-ketone and polyethersulfone, control mean polymerisation degree X
nIn the 2-200 scope.The present invention adopts mean polymerisation degree polyether-ether-ketone and polyethersulfone to meet and also can align the composition weight percent of multipolymer in addition, makes its polyether-ether-ketone: polyethersulfone is at 95-5: between the 5-95.
Example 1:
In three mouthfuls of reactors that stirring and backflow hydrophone are housed, add 0.5 mol, 4.4 ' dihydroxy diphenylsulphone and 0.45 molar 4.4 ' dichloro diphenyl sulfone and a certain amount of tetramethylene sulfone and the 100ml dimethylbenzene of accurate weighing.Under logical nitrogen, stir and be warming up to 80 ℃ of adding 1.0 molar NaOH aqueous solution, dimethylbenzene and water azeotropic reflux when continuing to be warming up to 116 ℃, from water trap, water is constantly told, when backflow dimethylbenzene clarification shows in the system anhydrous again generation, continuing to heat up steams dimethylbenzene, and keeps 12 hours (counting from NaOH) of reaction in 220 ℃.Polymkeric substance mucus is disperseed to precipitate into toner in water, water is boil-off repeatedly, can obtain two ends and be the mean polymerisation degree X of terminal hydroxy group
nBe that 19 polyethersulfone oligomer is standby.
Be equipped with in three mouthfuls of reactors of agitator at another.Add 0.5 mol, 4.4 ' difluoro benzophenone, 0.45 molar nitrogen quinone and a certain amount of sulfobenzide.Logical nitrogen adds 0.485 molar salt of wormwood after stirring down and being warming up to 180 ℃.Latter stage is warming up to 320 ℃ reaction 2 hours, keeps the hydroxyl-terminated polyether sulfone oligopolymer that will make at first under 320 ℃ the prerequisite afterwards again, 0.05 mol salt of wormwood and a certain amount of sulfobenzide slowly add and stir after reacted again 3 hours.Resultant of reaction is injected water cool off, and after pulverizing.Replace boil-off with acetone and water, can obtain polyether-ether-ketone/polyethersulfone segmented copolymer, its chain segment length is X
n=19, the composition weight ratio is a polyether-ether-ketone: polyethersulfone=38: 62.
Example 2:
Experimental procedure is fully with example 1, and just the ratio of components of synthesizing polyether sulfone oligopolymer to be changed into be 4.4 ' dihydroxy diphenylsulphone, 0.1 mol, 4.4 ' dichloro diphenyl sulfone, 0.092 mol, change the ratio of components of synthesis of polyether-ether-ketone oligopolymer into 4.4 difluoro benzophenones, 0.4 mol quinhydrones 0.392 mol gets final product.
The polyethersulfone chain segment length of the segmented copolymer that obtains is X
n=24, the chain segment length X of polyether-ether-ketone
n=99, it forms weight ratio is polyether-ether-ketone: polyethersulfone=72: 28.
Claims (3)
1, the present invention is that the technology of preparing of aromatic polyether-ether ketone copolymer is characterized in that polyether ether ketone oligomer and polyethersulfone oligomer copolymerization synthetic segmented copolymer.
2, as described in the right 1, it is characterized in that controlling X
nIn the 2-200 scope.
3, as it is characterized in that the weight percent of polyether-ether-ketone and polyethersulfone is 95-5 in the multipolymer as described in the right 1: between the 5-95.
