Abstract

The invention relates to an analysis method of acrylic resins and in particular relates to an analysis method of acrylic resin monomers in acrylic resin-containing mixtures. The analysis method is capable of determining the natures of the acrylic resin monomers and quantifying the acrylic resin monomers; the difficulty that the acrylic resin monomers only can be selectively quantified by nuclear magnetism is avoided; the analysis method is simple and convenient to operate without excessive precision operation requirements, wide in application range and suitable for all types of acrylic resins or acrylic resin-containing mixtures.

Description

[0001] technical field [0002] The present invention relates to a microscopic spectrum analysis method, in particular to an analysis method of acrylic resin, in particular, to an analysis method of acrylic resin monomer in a mixture containing acrylic resin. Background technique [0003] Acrylic resin is synthesized from common monomers and other monomers in different proportions. Acrylic resin can be composed of methyl acrylate, ethyl acrylate, n-butyl acrylate, methyl methacrylate, n-butyl methacrylate, Styrene, acrylic acid, methacrylic acid and its derivatives (such as esters, nitriles, amides) and other monomers are polymerized. If you want to understand acrylic resins, you need to accurately quantify the monomers in acrylic resins. Especially in a complex formulation system, rough quantification cannot meet the requirements of analysis. However, it is currently difficult to simultaneously analyze multiple components of congeners using chemical analysis and infrared s...
