Embodiment 1

[0020] Place 52ml of polyamino compound divinyltriamine in a 250ml three-necked flask, cool in an ice-water bath, and place in N 2 Under protection, use a constant pressure funnel to slowly add a mixed solution of 43ml methyl acrylate and 100ml methanol dropwise, and react at room temperature for 4 hours after the dropwise addition to obtain light yellow transparent AB 2 type monomer. Then it was transferred to a rotary evaporator eggplant-shaped flask, methanol was removed under reduced pressure, the temperature was raised to 150°C to continue the reduced-pressure reaction for 4 hours, and the reaction was stopped to obtain a viscous light yellow amino-terminated hyperbranched compound.

[0021] Put 10 g of the above-mentioned amino-terminated hyperbranched compound into a three-necked flask, add a certain amount of water to completely dissolve the amino-terminated hyperbranched compound, stir to dissolve, and then dropwise add 25 g of quaternizing agent glycidyl trimethyl ch...

Abstract

The present invention discloses amino end hyper-branched compound quaternary ammonium salt and the preparation method, pertaining to the art of macromolecular material technology. The method adopts the amino end hyper-branched compound as the matrix for quaternary ammoniation of the amido on the surface or grafting the quaternary ammonium salt, thus obtaining the polymerized quaternary ammonium salt. The preparation method is that the amino end hyper-branched compound is dissolved in deionized water and then a certain amount of quaternary ammoniation reagent is added; after being even mixed, the polymerized quaternary ammonium salt with characteristics of the hyper-branched compound and the polycation. The present invention has the advantages that the synthetic process is simple, the synthetic cost is relatively low, the product can be applied to cation modification of cellulose fiber and protein fiber, salt-free dyeing of active dyestuff, direct dyestuff, acid dyestuff, acid mordant dyestuff, etc., and the antiseptic performance and anti-UV performance of the fabric is enhanced. At the same time, the present invention is applied to sewage treatment agent, antibacterial agent, surface active agent, functional material forebody, medical carrier, etc.

Description

technical field [0001] The invention relates to a polyquaternary ammonium salt and a preparation method thereof, in particular to an amino-terminated hyperbranched compound quaternary ammonium salt and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] Due to its unique branched molecular structure, no entanglement between molecules, and a large number of end groups, hyperbranched compounds exhibit high solubility, low viscosity, high chemical reactivity, and other special features that many linear polymers do not have. These properties make hyperbranched polymers show attractive application prospects in many aspects such as polymer blending, coatings, films, polymer liquid crystals, and drug delivery systems. In addition, although the molecular structure of hyperbranched polymers is not as perfect as that of dendrimers, its synthesis often adopts a one-step method, which is simple and does not require tedious a...
