preparation example 1

[0023] Get 1.98 kilograms of polypropylene fat pellets (PP) and directly feed to the twin-screw extruder, then take 0.02 kilograms of acrylic acid (acrylic acid, AA) and 2 g of 2,5-dimethyl-2,5-bis(tert Butylperoxy)hexane (as a peroxide free radical initiator) was fed to the aforementioned twin-screw extruder in a side-feed manner. The temperature of the screw feed port is 200°C, the temperature of the injection section is 210°C, the screw speed is 200rpm, and the mixing time is about 1 minute. Finally, the finished product is cooled and granulated with water to obtain polypropylene (PP- AA) color masterbatch, the weight percent of reactive groups is about 1wt%.

preparation example 2

[0025] Get 1.98 kg of polypropylene pellets (PP) directly into the twin-screw extruder, then take 0.02 kg of maleic anhydride (maleic anhydride, MAH) and 2 g of 2,5-dimethyl-2,5 - Di(tert-butylperoxy)hexane (as peroxide radical initiator) was fed as side feed to the aforementioned twin-screw extruder. The temperature of the screw feed port is 200°C, the temperature of the injection section is 210°C butene, the screw speed is 200rpm, and the mixing time is about 1 minute. Finally, the finished product is cooled and granulated with water to obtain a maleic anhydride derivative group. Polypropylene (PP-MAH) liposomes, the weight percent of reactive groups is about 1wt%.

preparation example 3

[0028] Get 1.98 kilograms of EPDM rubber (EPDM, product number KEP2320, sold by KUMHO) directly into the twin-screw extruder, then get 0.02 kilograms of maleic anhydride (maleicanhydride, MAH) and 2g of 2,5 - Dimethyl-2,5-bis(tert-butylperoxy)hexane (as peroxide free radical initiator) was fed as side feed to the previously described twin-screw extruder. The temperature of the screw feed port is 200°C, the temperature of the injection section is 210°C, the screw speed is 200rpm, and the mixing time is about 1 minute. Finally, the finished product is cooled and granulated with water to obtain three For ethylene-propylene-diene rubber (EPDM-MAH) liposomes, the weight percent of reactive groups is about 1wt%.

Abstract

The present invention discloses a compatibilizer and a thermoplastic resin composition comprising the same. With reactive groups of the polyolefin compatibility agent comprises 100 parts by weight of (polyolefin); and 80 to 120 parts by weight of a copolymer, wherein the copolymer has a repeating unit of X (imgfile wi = 'DDA0000915487240000011.TIF' = '438' = 'he' / 140) y repeat unit (imgfile = 'DDA0000915487240000012.TIF' wi = '302' = '215') he / Z repeat units (imgfile = 'DDA0000915487240000013.TIF' wi = '337' = '211' / he) to And end groups (imgfile = 'DDA0000915487240000014.TIF' wi = '408' = 'he' / 281) in which X, y and Z separately and for the integers greater than or equal to 1, and X / (x + y + Z) between 0.5 and 0.7, Y / (x + y + Z) between 0.1 and 0.2, and Z / (Xyz) between 0.1 and 0.4.

Description

technical field [0001] The invention relates to a compatibilizer and a thermoplastic resin composition containing it. Background technique [0002] Polymer blends are widely used today, and the inherent immiscibility of the polymer components in most polymer blends can easily lead to phase separation in the blend polymer, and there are obvious interfaces between the polymer components. It is easy to affect the mechanical properties. [0003] Therefore, overcoming the problems created by intrinsically immiscible polymer blends is an important issue. Contents of the invention [0004] The invention discloses a compatibilizer, which comprises the following components or the reaction product comprising the following components: 100 parts by weight of polyolefin with reactive groups; and about 80-120 parts by weight of a copolymer, wherein the copolymer has x repeating units y repeat units z repeating units and end groups Wherein x, y and z are independent and are int...
