Embodiment 1

[0063] Styrene, acrylonitrile and methacrylic acid are firstly refined by vacuum distillation, and maleic anhydride and benzoyl peroxide are refined by recrystallization.

[0064] In a 4-necked glass bottle with a volume of 1 liter, add 225 grams of butanone and 125 grams of toluene, then add 70 grams of refined styrene, 25 grams of acrylonitrile and 10 grams of methacrylic acid in sequence, and finally add 0.3 grams of refined The obtained benzoyl peroxide was completely dissolved and mixed uniformly to obtain solution B. The glass bottle was heated in an oil bath at 120° C. and the mixture in the glass bottle was stirred with a stirrer at a stirring rate of 120 rpm.

[0065] Then the A solution made of 33 grams of styrene obtained after the refining treatment, 65 grams of acrylonitrile, 4 grams of maleic anhydride and 0.3 grams of benzoyl peroxide was slowly added dropwise to the glass bottle, and the time of dropping was 6 hours. During the dropwise addition process, the gl...

Embodiment 2

[0067] The preparation method is the same as in Example 1, wherein 6 grams of methacrylic acid, 0.6 grams of benzoyl peroxide, and 2 grams of maleic anhydride are added, and the addition amounts of the remaining components are the same as in Example 1, and the final product is identified as ASA2.

Embodiment 3

[0069] The preparation method is the same as in Example 1, wherein 2 grams of methacrylic acid, 0.8 grams of benzoyl peroxide, and 1.5 grams of maleic anhydride are added, and the addition amounts of the remaining components are the same as in Example 1, and the final product is marked as ASA3.

Abstract

The invention relates to a copolymer compatilizer applied in the composite ABS and a composite composed of the compatilizer, ABS and thermoplastic resin. The copolymer compatilizer is a tetrabasic random copolymer, and which is polymerized by the aromatic series vinyl monomer, the cyaniding vinyl monomer, the Alpha, Beta-unsaturated dicarboxylic anhydride monomer and the Alpha, Beta -unsaturated fatty acid monomer and the polymerized, and through the mass polymerization, Solution Polymerization or emulsion polymerization. When the random copolymer is as a compatilizer applied in the composite comprised of ABS and polyamide, polyimide, polycarbonate, polyester, biodegradable polyesters, polyformaldehyde, polymethyl methacrylate or fibrin, the resistance of the composite, stability of the melt and process ability can be greatly improved.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a copolymer compatibilizer applied to ABS compositions and an ABS composition containing the compatibilizer. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer (ABS) has excellent mechanical properties balanced by toughness, hardness and rigidity, such as excellent electrical properties, wear resistance, dimensional stability, chemical resistance and surface gloss, etc., and Easy to process and shape. However, its weather resistance, heat resistance and flame retardancy still need to be improved. [0003] A polymer composition is a composite system composed of two or more polymer materials, and is composed of two or more different types of resins (or resin and rubber, or resin and thermoplastic elastomer) and other additives. A polymer composition formed by blending and compounding in a molten or viscous state. ABS is often combined with other engineering ...
