preparation example 1

[0043] A certain amount of carboxyl-terminated liquid polybutadiene (Shandong Qilong Chemical Co., Ltd., the number of repeating units is 100) and an equimolar amount of glycidyl acrylate are added to the reactor, and then 3% of the total mass of the reactants The catalyst 4-dimethylaminopyridine and the solvent toluene with a mass ratio of 1:1 to the total reactants were added into the reaction kettle, mixed evenly, heated to 100°C under stirring, and reacted for 5 hours. Then discharge, remove the solvent and unreacted reactant and catalyst. The resulting product was dried at 120°C to constant weight to obtain Functionalized Liquid Polybutadiene Example 1.

preparation example 2

[0045]Add a certain amount of hydroxyl-terminated liquid polybutadiene (Shandong Qilong Chemical Co., Ltd., the number of repeating units is 50) and glycidyl methacrylate into the reactor, wherein the hydroxyl-terminated liquid polybutadiene and methacrylic acid The ratio of glycidyl ester is 1:1.2, then will account for the catalyst 4-dimethylaminopyridine of reactant gross mass 4% and be 3:2 solvent hexanaphthene with reactant gross mass ratio to join in the reactor, mix Evenly, the temperature was raised to 110°C under stirring, and the reaction was carried out for 4 hours. Then discharge, remove the solvent and unreacted reactant and catalyst. The resulting product was dried at 120°C to constant weight to obtain functionalized liquid polybutadiene Example 2.

preparation example 3

[0047] A certain amount of hydroxyl-terminated liquid polybutadiene (Shandong Qilong Chemical Co., Ltd., number of repeating units is 30) and maleic anhydride are added in the reactor, wherein the ratio of hydroxyl-terminated liquid polybutadiene and maleic anhydride is 1:1.1. Then, the catalyst pyridine accounting for 6% of the total mass of the reactants and the solvent cyclohexane with a ratio of 2:1 to the total mass of the reactants were added into the reactor, mixed evenly, and heated to 110° C. under stirring, and reacted for 4 hours. Then discharge, remove the solvent and unreacted reactant and catalyst. The resulting product was dried at 120°C to constant weight to obtain functionalized liquid polybutadiene Example 3.

[0048] Other functionalized liquid polybutadienes used in the following examples were prepared as described above except using different numbers of repeating units of hydroxyl terminated liquid polybutadienes, different anhydrides or acid esters.

Abstract

The invention relates to a copolymer compatilizer. Copolymer comprises 50-80wt% of alkenyl monomer of with solubility parameter between 16.5-23(MPa)1 / 2, 0.1-10wt% of functional monomer and 10-40wt% offunctionalized liquid polybutadiene. Structure of the copolymer compatilizer is shown as follows, wherein R1 refers to -H or -COOH, R2 refers to -H or -CH3, X refers to -OH, -COOH or -NH2, and repeating unit number n is an integer between 10 and 200. The invention further provides a preparation method and application of the copolymer compatilizer. Compared with the prior art, the trielement copolymer has the advantages that the copolymer can be stably distributed on two-phase interfaces of polyester or polyamide and ABS, can improve phase morphology and improve mechanical performance of alloy, especially impact performance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a copolymer compatibilizer and its preparation method and application, which can be used to improve compatibility and improve the performance of blended materials. Background technique [0002] Polymer alloy technology can improve the performance of polymer materials, reduce production conditions and realize the functionalization and high performance of polymer materials. It plays an irreplaceable role in the fields of polymer science and polymer material engineering. [0003] It is generally believed that in order to ensure an excellent blending effect, the components of the polymer alloy must have good compatibility, and the following principles should be considered when selecting the resin: the principle of polarity matching, the principle of similar surface tension, the principle of similar diffusion ability, The principle of equal viscosity and the principle of sim...
