Abstract

The invention relates to acrylic macromolecular surfactant and a method for making the porous resin of the same, belonging to the organic macromolecular compound field. The acrylic macromolecular surfactant comprises 93 to 97 percent of acrylic substance, 3 to 7 percent of vinyl ion reagent and 0.5 to 1 percent of initiator. The substances are added in a reactor containing an amount of water, and are reacted at a temperature controlled between 57 and 80 DEG C for 6 to 24 hours; then, the reactants undergo acetone deposition, ether scrubbing and deposition and vacuum drying. The porous resin is made through adopting the following steps that: the acrylic macromolecular surfactant, monomer, initiator and a crosslinking agent are added in water, cyclohexane or the mixed solution of water and cyclohexane; and round porous resin is made by means of emulsion polymerization under the action of the initiator. The method makes the porous resin by means of the acrylic macromolecular surfactant, wherein the surfactant has excellent performances and full emulsification; and the porous resin is round in shape with the diameter ranging between 50 and 500 micron. The porous resin made by the method contains active epoxy group, and can be used in the fields of enzyme immobilization, antibody adsorption and purification and blood pathogen or toxin cleaning, etc.

Description

technical field [0001] The preparation method of the acrylate polymer surfactant and the porous resin of the present invention belongs to the field of organic polymer compounds. Background technique [0002] With the in-depth research in the fields of environmentally friendly water-soluble coatings, enhanced oil recovery, drug carriers, biomimicry, medical polymer materials, and emulsion suspension polymerization, higher requirements are placed on the diversity and performance of surfactants, among which polymer surface Activity is increasingly becoming the focus of attention. Compared with low-molecular surfactants, high-molecular surfactants have a higher molecular weight and can form unimolecular micelles or multi-molecular micelles. The solution has high viscosity and good film-forming properties, and has good dispersion, emulsification, thickening, Stability and flocculation performance. At present, polymer surfactants are widely used in many important basic industrie...
