Abstract
The invention discloses high-liquidity poly(phenylene ether sulfone ketone) (PPSUK) resin with light color and narrow molecular weight distribution. The resin is prepared by introducing an aromatic ketone monomer, especially heterogeneous aromatic ketone monomer into a PPSU polymer to polymerize by using sulfobenzide as a solvent, wherein the main molecular chain obtained by polymerization contains a polyether sulphone and polyaryletherketone random copolymerized structure, and the molar ratio of -SO2- group to -CO- group is (1-9):1. The prepared polymer has a processing molding temperature not higher than 350 DEG C generally, has high liquidity, easy to process, has excellent solvent resistance, and can be used for enlarging the product application field.
Description
Technical field
The invention belongs to synthetic resins field, be specifically related to a kind of high-flow polyphenylene ether sulfone ketone resin and preparation method thereof.
Background technology
Polyether sulphone is a kind of high performance engineering plastics, because they have thermotolerance, hot water resistance, creep resistance, dimensional stability, shock-resistance, chemical proofing, the excellent over-all properties such as nontoxic, fire-retardant, thus for a long time electronics, electrical equipment, machinery, automobile, medical apparatus, food-processing and not the field such as stickness paint be widely used.
Industrial important polyether sulphone comprises polyethersulfone (PES) and biphenyl polyether sulfone (PPSU), all has very high second-order transition temperature (-220 DEG C).In use, because polyether sulphone has higher melt viscosity, be not easy the product of molding structure complexity, and in moulding product, have bubble, the defect such as hollow, therefore in the urgent need to improving its processing fluidity, thermal characteristics and don't the impact transparency of its excellence can be kept simultaneously, expand its range of application.In addition, polyether sulphone is more responsive to some chemical solvents, and pressure embrittlement problem easily occurs.
Copolymerization is a kind of effective ways changing molecular structure, if Chinese patent CN200910217764 is by biphenyl sulfone ether and polyethersulfone terpolymer, can change the Tg of polymkeric substance.American documentation literature US20100310804A1 discloses a kind of method of ketone group containing polyether sulphone, it take sulfobenzide as solvent, the mixture of sodium carbonate and salt of wormwood is salt forming agent, 275 DEG C of polyreactions, later stage adds end-capping reagent, anti-depolymerizing agent etc., prepare the PPSK of fusing point 319-360 DEG C, but its industrial process unexposed.This technical disadvantages need add a certain amount of anti-degradation agents when being the end-blocking dosage that phase after the reaction adds and reacting weight monomer, makes system more complicated, and increase the difficulty for the treatment of and finishing section, technique relative complex, product color are darker.
Chinese patent literature CN102757561A discloses a kind of ketone group containing polyethersulfone resin, mol ratio containing sulfone monomer and ketone group containing monomer is 9:1-1:1, and it take tetramethylene sulfone as solvent, and toluene is a point aqua, potassium hydroxide solution is salt forming agent, but its industrialized preparing process unexposed.In actual production and application, the polyether sulphone not adding ketone group monomer is amorphous, and because the viscosity of itself is higher, thus processing temperature, more than 360 DEG C, reaches 380 DEG C or higher, therefore can not apply in some industry usually.There is regular phenomenon in the ternary or the multi-component copolymer polyether sulphone that add ketone group monomer, have fixing fusing point, the introducing due to ketone group adds the regularity of molecule, and its mobility have also been obtained raising.When ketone group containing monomer ratio is greater than 30% of sulfuryl monomer and ketone group monomer sum, polyreaction can more difficult, polymerization produce cycle longer, thus product color and the higher problem of fusing point can be caused, especially when ketone group containing monomer ratio is greater than 40% of sulfuryl monomer and ketone group monomer sum, lower than at the temperature of 240 DEG C, polyreaction occurs hardly.When ketone group containing monomer ratio is greater than 25% of sulfuryl monomer and ketone group monomer sum, the Tm of the random copolymers of gained is greater than 350 DEG C, and its processing temperature of the product of gained can reach 380 DEG C or higher equally, thus causes processing difficulties, is difficult to be widely used.In addition, the transparency of its product also has certain decline.Therefore, controlling ketone group containing monomer ratio in the reasonable scope, is the scheme of poly (aryl ether sulfone ketone) simple possible developing high workability, easily processing, chemical solvent resistance energy and radiance.
There is following shortcoming in the existing technique of commercial process sulfolan solvent system: (1) adopts the technique alkalescence that alkali metal hydroxide (KOH or NaOH) is salt forming agent excessively strong, have water existent condition at high temperature, excessive KOH or NaOH be completely with metal ion and OH
-form exists, and tetramethylene sulfone easily decomposes, and causes the disadvantageous effects such as system is complicated; (2) KOH or K is adopted
2cO
3as salt forming agent, then resin can be caused to contain potassium end group, resin stability when high temperature process is shaping is reduced; (3) polymeric reaction temperature is lower, and molecular weight distribution is wider; (4) tetramethylene sulfone has a certain amount of decomposition, causes that product color is dark and acid number is higher.
