Embodiment 1

[0029] Take by weighing 34.5g maleic rosin ethylene glycol acrylate, be dissolved in 138g ethyl acetate, use ultrasonic wave to promote dissolution, after cross-linking agent dissolves completely, then add 47g methacrylic acid, 2.3g methyl methacrylate, 27g of soybean oil and 4g of azobisisobutyronitrile were oscillated by ultrasonic waves for 10 minutes to disperse evenly to obtain an oil phase; another 510g of distilled water was added to a three-necked flask, and 0.5g of sodium lauryl sulfate was added and mixed to obtain a water phase Mutually. Adjust the stirring speed to 300rpm, and add the fully dissolved oil phase to the water phase at a constant stirring speed. After adding the organic phase, the system is pre-dispersed at room temperature for 10 minutes to form a better dispersion system. Start slowly heating up, and react at a constant temperature at 80°C 20min, the heating rate is 5°C / 10mim; then the temperature is raised to 95°C at the same heating rate, and the t...

Embodiment 2

[0032] Weigh 34.5g of maleic rosin ethylene glycol acrylate, dissolve it in 35g of ethyl acetate, and use ultrasonic waves to promote dissolution. After the crosslinking agent is completely dissolved, add 0.5g of acrylic acid, 13g of methyl methacrylate, 2.4g of Soybean oil and 0.24g of benzoyl peroxide were oscillated by ultrasonic waves for 10 minutes to disperse evenly to obtain an oil phase; another 680g of distilled water was added to a three-necked flask, and 0.07g of sodium lauryl sulfate was added and mixed to obtain an aqueous phase . Adjust the stirring speed to 250rpm, add the fully dissolved oil phase to the water phase at a constant stirring speed, according to the operation of Example 1, after the reaction is completed, filter, wash with 95 ° C distilled water until the washing liquid is clear, and obtain horse Lyrosin ethylene glycol acrylate-acrylic acid-methyl methacrylate copolymer.

Abstract

The invention discloses an abietyl-containing terpolymer and a preparation method thereof, the chemical name of the abietyl-containing terpolymer is maleic rosin ethylene glycol acrylate-(methyl) acrylic acid-methyl methacrylate polymer. The preparation method is as follows: taking maleic rosin ethylene glycol acrylate, (methyl) acrylic acid and methyl methacrylate polymer as raw materials, and ethyl acetate as solvent, preparing the maleic rosin ethylene glycol acrylate-(methyl) acrylic acid-methyl methacrylate polymer by using a suspension polymerization method under the action of an initiator. The polymer has -COOH radicals, can be used for natural product separation such as separating berberine hydrochloride, ligustrazine hydrochloride and the like and used as the carrier of immobilized enzymes such as immobilized amylase, lipase and laccase.

Description

technical field [0001] The invention relates to a high molecular polymer and a preparation method thereof, in particular to a rosin-based terpolymer of the invention. Background technique [0002] A terpolymer containing a rosin base in the present invention is a new functional-based high polymer, and the material and its preparation method have not been reported so far. Contents of the invention [0003] The purpose of this invention is to provide a kind of terpolymer containing rosin base and its preparation method, this copolymer has -COOH functional group, has wide application, can be used for natural product separation, for example is used for separating berberis hydrochloride alkali, ligustrazine hydrochloride, etc.; and carriers for immobilizing enzymes, such as carriers for immobilizing amylase, lipase, and laccase. [0004] The present invention has two contents: 1. Contents of the invention 1 [0005] 1) The chemical name of a kind of rosin-containing terpoly...
