W1A/ POE-g-MAH serious maleic anhydride grafted POE used as compatibilizer coupling agent for Polyamides/ Nylon/PA glass fiber

W1A is prepared by grafting maleic anhydride by POE reaction. Since it introduces a strongly polar side group (maleic anhydride) on the main chain of POE molecule, maleic anhydride grafted POE can become a polar material. A bridge for adhesion and compatibility with non-polar materials. In the application of nylon + glass fiber modification, it can react with the glass fiber after surface treatment to improve the compatibility of nylon and glass fiber, thereby improving the tensile strength and impact strength of nylon. W1A can be used as both a compatibilizer and a toughening agent. As a nylon compatibilizer, it is also suitable for PA/PE and PA/PP alloys, which can improve the toughness of the alloy. As a nylon toughening agent, its low temperature The performance is very superior, the impact strength of PA6+15%W1A at -40ºC can be maintained at 35-40% of the impact at room temperature.

Typical application:

1. Nylon toughening reinforcement
2. Nylon composite filling
3. Nylon, polypropylene, polyethylene mixed with gold compatibilizer

Reaction principle

POE is a random copolymer elastomer of ethylene and high-carbon α-olefins (1-butene, 1-hexene, 1-octene, etc.) catalyzed by metallocene catalysts. It has excellent mechanical properties, rheological properties and UV light resistance. In addition, POE also has the advantages of good affinity with polyolefins and good low temperature toughness, and is widely used in the toughening and modification of non-polar polymers such as polypropylene (PP) and polyethylene (PE).

POE is a non-polar elastomer with poor compatibility with polar materials, which is not conducive to the modification and reinforcement of polar polymers such as polyamide (PA) and polyethylene terephthalate (PET). The common practice is to first carry out graft modification on POE, and graft low molecular weight compounds containing polar functional groups on the macromolecules, thereby changing the polarity of the POE molecular chain and improving its compatibility with polar polymers. , so that it can be applied to the modification of polar polymers. Commonly used grafting monomers for POE are maleic anhydride (MAH), glycidyl methacrylate (GMA), methacrylic acid (MAA), acrylic acid (AA) and the like.

POE-g-MAH (POE grafted maleic anhydride) is obtained by grafting highly reactive maleic anhydride (MAH) monomer by reactive extrusion with POE elastomer as matrix. POE-g-MAH can be used as a good toughening agent and compatibilizer. Its toughening effect is better than that of pure POE without grafting. It is suitable for PA, PP, PE, PC, ABS, PET, PBT, etc. Compatibility and toughening of its alloy materials.
