Hydroquinone Monomethyl Ether

It is a phenolic polymerization inhibitor with white to light yellow crystals. All types of organic solvents and monomers have extremely high solubility. Added to each polymer formula to maintain thermal storage stability and effectively inhibit viscosity increase, but does not affect photopolymerization efficiency. It is light in color, does not turn yellow when cured, is safe and environmentally friendly, has no irritating odor or migration and release of harmful substances, and can be used in medical and health care and food packaging products.

The chemical structure of hydroquinone monomethyl ether contains one hydroxyl group (OH) in the hydroquinone molecule replaced by a methoxy group (OCH3). Polymerization inhibitor for acrylonitrile, acrylic acid and their esters. There is no need to remove the ether when using it, and it can directly participate in polymerization. It is also used in the synthesis of antioxidants, plasticizers and food additives.

F: Is there anything I need to pay attention to when using this product?

Q: This type of product is a polymerization inhibitor that is widely used and has good effects. However, it should be noted that the polymerization inhibitory effect will only show when oxygen is dissolved in the monomer. The phenols in the product are oxidized into the corresponding quinones, which combine with the free radicals of the chain to inhibit polymerization.

F: In what specific areas can the product be applied?

Q: Used as a polymerization inhibitor for styrene, acrylic esters, acrylonitrile and other vinyl monomers, and also as a terminator for grafted chloroprene adhesives. When trace amounts of sulfur dioxide are mixed with the product, it can also be used as a polymerization inhibitor for cyanoacrylate quick-drying adhesive.
