Problems solved by technology

Although polyether sulfone ketone has excellent comprehensive properties, most of the synthetic polyether sulfone ketones use fluorine-containing monomer copolymerization method at present, (Rose J B.ThermoplasticAromatic Polyetherketones.USA Pat, CO8G 65 / 40, 4320224.1982-05-16, NewtonA B.Aromatic Polymer.Eur Pat, CO8G 65 / 40, 278720A2.1988-08-03) cause the cost is too high, it is difficult to realize industrialization, and it also limits the application in some fields

[0032] Synthesis of Example 1 PPEKS

[0033] In a four-necked flask with a stirrer, a thermometer, a reflux condensing device, a water separator, and a nitrogen pipe, under nitrogen protection, add (26.1 g) of 1-(p-chlorobenzoyl chloride)-3- (p-Chlorobenzenesulfonyl chloride) benzene and (15.2g) of bisphenol A, (16.4g) of anhydrous potassium carbonate, add 100ml of DMAC, 75ml of toluene, heat to reflux, start to separate water at about 130 ° C, separate After the water is complete, the temperature is gradually raised to 155°C, and the color of the reaction system changes from yellow to brown at this time. After reacting at this temperature for more than 10 minutes, cool down to about 130°C and then add toluene to ensure that the water is completely taken away, then slowly raise the temperature to 155°C for polycondensation reaction, and reach the predetermined viscosity when the reaction liquid becomes viscous (0.60 ~1.30dL / g), stop the reaction, lower the temperature to 100°...

Chlorobenzenesulfonyl chloride) benzene and 15.2g of bisphenol A, 15.5g of anhydrous potassium carbonate, add 100ml of sulfolane and 75ml of toluene, heat to reflux, start water separation at about 130°C, and gradually heat up to 160°C after water separation is complete , the color of the reaction system changed from yellow to brown. After reacting at this temperature for more than 10 minutes, lower the temperature to about 130°C and then add toluene to ensure that the water is completely taken away, and then slowly raise the temperature to 155°C for polycondensation reaction. Others are the same as example 1.

Abstract

The invention discloses a synthesizing method of asymmetrical meta-position polyarylethersulfoneketone in the main chain, which comprises the following steps: adding 1-(p-chlorobenzoylchlorine)-3-(p-chlorobenzenesulfonatechlorine) benzene, bisphenol A, anhydrous potassium carbonate, reacting dielectric and wet agent in the reacting bottle; heating to reflux; dividing water at 130-150deg.c; heating to 130-170 deg.c; polymerizing; cooling to 100 deg.c after viscosity reaches 0.60-1.30dL / g; pouring reacting liquid into boiled water to sediment; obtaining white bar material.

Description

technical field [0001] The invention belongs to the field of organic polymer compounds. It relates to polymer compounds obtained by reactions other than carbon-carbon unsaturated bonds, especially to the synthesis of high-molecular compounds containing aryl ether sulfone ketone structures from dichloro monomers containing asymmetric sulfone and ketone structures, bisphenols and bisphenol-like compounds. molecular compound. Background technique [0002] Polyarylether is a new type of thermoplastic heat-resistant special engineering plastic developed in the past 40 years. Polyarylether sulfone and polyarylether ketone are the two main types of polyarylether (May R. . Edited by Kroschwitz J.I., John Wiley & Sons, New York: 1991, 769). It has excellent comprehensive properties, including mechanical properties, electrical properties, and heat resistance, and can be used for a long time in mechanical stress and harsh chemical and physical environments (May R.In highperformance p...
