Abstract

The invention relates to a preparation method of cellulose-g-resin acid grafted copolymer. The preparation method of the cellulose-g-resin acid grafted copolymer comprises the steps that cellulose atom transfer radical polymerization (ATRP) macroinitiator is synthesized by reaction of cellulose and 2-Bromoisobutyryl bromide in a homogeneous solution system; resin acid monomer, cellulose ATRA macroinitiator, catalytic agents, ligand and rosinyl monomer good solvent are added to a reaction bulb, fully stirred, and dissolved, freezing is carried out for three times, oxygen in the mixed solution is removed in a circulation process of vacuum pumping and nitrogen filling, after the reaction is carried out for 1-24 hours at the temperature of 50-120 DEG C, the polymer is enabled to be deposited in methanol, filtered, and dried, and finally the cellulose-g-resin acid grafted copolymer is obtained. According to the preparation method of the cellulose-g-resin acid grafted copolymer, cellulose-g-resin acid grafted copolymer with different molecular weights and different molecular weight distributions can be obtained. The cellulose-g-resin acid grafted copolymer can be used for improving tenacity of materials by serving as functional additive agents.

Description

technical field

[0001] The invention relates to a preparation method of a cellulose-g-resin acid graft copolymer, in particular to a compound method of a natural compound and a natural polymer.

[0002] Background technique

[0003] Cellulose is the most abundant and oldest natural polymer in the world, and it is the main component of plant skeleton. The annual cellulose content produced by plants on the earth is about 1.5×10 12 Ton, it has the advantages of wide source, degradable, non-toxic, good biocompatibility, etc., and has a good application prospect in the field of new materials. The molecular formula of cellulose macromolecule is: (C 6 h 10 o 5 ) n , is a macromolecular polysaccharide composed of D-glucose with β-1,4 glycosidic bonds, with a molecular weight of about 50,000 to 2,500,000. There are three polar hydroxyl groups in each glucose unit in the cellulose macromolecule, and there are no branches in the main chain of the macromolecule. The phenomenon o...
