Abstract

The invention relates to an insoluble infusible metal-modified cross-shaped esterified product and a preparation method thereof. The insoluble infusible metal-modified cross-shaped esterified productis prepared by dripping a metal acetate solution into the cross-shaped esterified product solution, wherein the prepared metal-modified cross-shaped esterified product is a network polymer formed by cross-linking the cross-shaped esterified product and metal ions; the metal-modified cross-shaped esterified product has the characteristic of insolubility and infusibility, is insoluble in an organicsolvent I below 80 DEG C, and does not melt in the range of room temperature to T, wherein the T > / = 380 DEG C, and the organic solvent I is an aromatic hydrocarbon solvent, an aliphatic hydrocarbon solvent, an alicyclic hydrocarbon solvent, a halogenated hydrocarbon solvent, an alcohol solvent, an ester solvent, a ketone solvent, acetonitrile, pyridine, phenol, N, N-dimethylformamide or N, N-dimethylacetamide. The preparation method has simple process and low cost; the prepare product has the characteristics of insolubility and infusibility, and solves the problems of high solubility and lowmelting point of the existing functional cross-shaped esterified product.

Description

technical field [0001] The invention belongs to the technical field of polymer blending, and relates to an insoluble and infusible metal-modified cruciform ester compound and a preparation method thereof. Background technique [0002] With the development of my country's synthetic materials industry and the continuous expansion of application fields, polymer materials such as polyester have been widely used in various fields such as chemical building materials, electronic appliances, transportation, aerospace, daily furniture, interior decoration, and basic necessities of life. Higher demands are placed on the functionality of synthetic materials. Functional modification of polymers has become a hot research direction at present. [0003] Ester compounds are often used as functional modification carriers because they are similar in structure to polyester and other polymers and have good compatibility. Researchers often perform functional modification on esterified compound...
