Methyl Polyethyleneglycol Methacrylate 2000 (MPEGMA 2000)

Methyl Polyethyleneglycol Methacrylate 2000 (MPEGMA 2000) is an ester of Methacrylic Acid and is used as a raw material component in the synthesis of polymers. The ester is a monofunctional monomer consisting of a methacrylate group with a characteristic high reactivity and a long hydrophilic moiety. It forms homopolymers and copolymers. Its copolymers can be prepared with (meth)acrylic acid and its salts, amides, and esters as well as with acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene and with other monomers.

Methyl Polyethyleneglycol Methacrylate 2000 (MPEGMA 2000) is also a very useful feedstock for chemical syntheses because it readily undergoes addition reactions with a wide variety of organic and inorganic compounds.

The introduction of Methyl Polyethyleneglycol Methacrylate 2000 (MPEGMA 2000) in polymers provides them with:

  • Hydrophilicity
  • Rheology modification (associative thickening)
  • Flexibility
  • Dispersibility
  • Low shrinkage

In order to prevent polymerization Methyl Polyethyleneglycol Methacrylate 2000 (MPEGMA 2000) must always be stored under air, and never under inert gases. The presence of oxygen is required for the stabilizer to function effectively.Freezing of Methyl Polyethyleneglycol Methacrylate 2000 (MPEGMA 2000) results in the segregation of monomer and inhibitor. In addition, it is especially important to replenish dissolved oxygen after melting the drummed material prior to use. Replenishment dissolved oxygen and mixing of MEHQ into the monomer can be done using a palette shaker or a drum tumbler.The melting process requires temperatures of 20 °C or higher but at a maximum of 35 °C as the heating temperature. Warming the product in a room of 20 – 25 °C over several days is the preferred option. As an alternative, if faster melting is required heating cabinets using hot water or hot oil are the preferred apparatus for the thawing process of Methyl Polyethyleneglycol Methacrylate 2000 (MPEGMA 2000) since this avoids hot spots. Local hot spots of more than 35 °C may result in premature aging of the material. Product temperatures of more than 45 °C may result in polymerization of the monomer.During storage as a molten liquid, it is advisable to replenish the dissolved oxygen content on a weekly basis. Methyl Polyethyleneglycol Methacrylate 2000 (MPEGMA 2000) has to contain a stabilizer and the storage temperature must not exceed 20 °C to prevent premature quality degradation. If the above-mentioned conditions are met a storage stability Methyl Polyethyleneglycol Methacrylate 2000 (MPEGMA 2000) of 6 months can be expected upon delivery.
