Embodiment 1

[0044] 50g of methyl methacrylate, 30g of butyl acrylate and 20g of 2-methyl-2-adamantyl methacrylate were placed in a four-necked flask containing 400g of tetrahydrofuran solvent, and stirred until the monomers were uniformly mixed;

[0045] After methyl methacrylate, butyl acrylate and 2-methyl-2-adamantyl methacrylate are dissolved, add 2 g of tert-butyl peroxybenzoate, stir until dissolved, and obtain a mixed solution;

[0046] Place the four-necked flask containing the mixed solution in an oil bath equipped with a magnetic stirrer. After installing the condensing pipe and the nitrogen interface, turn on the condensed water, pass in nitrogen, turn on the magnetic stirrer and put the oil bath in the pot. The temperature rises to the boiling point of the solvent, about 66°C. After the boiling phenomenon occurs, the polymerization reaction starts, and the reaction is carried out for 20 hours to obtain a reaction solution;

[0047] Cool the reaction solution, place the reactio...

Abstract

The invention is applicable to the field of polymer materials, and provides a method for removing small molecular substances in synthetic resins, comprising the steps of: mixing a monomer and an initiator to obtain a mixed solution; subjecting the mixed solution to a polymerization reaction to obtain a reaction solution , the reaction solution contains macromolecular synthetic resins and small molecular substances, and the small molecular substances include small molecular synthetic resins and / or monomers that do not participate in the reaction; the reaction solution is added to the electrospinning device, and the electrospinning The needle outlet of the silk device is placed above the container containing the lotion, the electrospinning device is turned on, and the reaction solution is pushed forward. When droplets appear on the needle, a voltage is applied to the needle to form a spray and enter the lotion. The small molecules of the substance are dissolved in the lotion, and the macromolecular synthetic resin forms a precipitate, which is a narrow distribution of synthetic resin. The method of the present invention can form a spray with small particle size, and can effectively remove the small molecular substances in the synthetic resin.

Description

technical field [0001] The invention belongs to the field of polymer materials, and particularly relates to a method for removing small molecular substances in synthetic resins. Background technique [0002] Synthetic resin is a kind of artificially synthesized high molecular weight polymer, which is a kind of resin that has the same or exceeds the inherent characteristics of natural resin. At present, synthetic resins are widely used in the fields of electronics, electrical appliances, automobiles, furniture, toys, entertainment products, household appliances and medical supplies. [0003] The molecular groups connected to the synthetic resin and the size of the molecule determine the performance of the synthetic resin to a large extent. For example, studies have shown that the molecular groups connected to the photoresist resin and the molecular size of the photoresist resin determine the resolution and etching resistance of the photoresist resin to a large extent. The m...
