Stearyl Polyethyleneglycol Methacrylate 1100 (SPEGMA 1100)

Stearyl Polyethyleneglycol Methacrylate 1100 (SPEGMA 1100) 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 cyclic hydrophobic group. It forms homopolymers and copolymers which can be obtained with acrylic acid and its salts, amides, and esters, as well as methacrylates, acrylonitrile, maleic esters, butadiene, and other monomers.

Stearyl Polyethyleneglycol Methacrylate 1100 (SPEGMA 1100) easily entering into the reaction of accession with a wide range of organic and inorganic substances, is used for the synthesis of organic low molecular weight substances.

Product type: PEG Methacrylate Monomer

The introduction of Stearyl Polyethyleneglycol Methacrylate 1100 (SPEGMA 1100) in polymers provides them with:

  • Hydrophobicity
  • Hydrophilicity
  • Rheology modification (associative thickening)
  • Low (Tg) glass transition temperature
  • Low volatility due to high molecular weight

Characteristics:

  • Stearyl Polyethyleneglycol Methacrylate 1100 (SPEGMA 1100) is a structure-activity relationship in associative thickening: in alkaline soluble emulsions/polymers, small amounts of hydrophobic comonomers like SPEGMA interact with each other and create thickening when interacting with other monomer chains.

The areas of applications:

  • Stearyl Polyethyleneglycol Methacrylate 1100 (SPEGMA 1100) is used in the preparation of solid polymers, acrylic dispersions, and polymer solutions, which are used in various industries.

It is applied in the production of:

  • Coatings

To avoid polymerization, Stearylpolyethyleneglycol Methacrylate 1100 (SPEGMA 1100) should always be stored in air and not under inert gases. For the effective functioning of the stabilizer, the presence of oxygen is necessary. Freezing of Stearylpolyethyleneglycol Methacrylate 1100 (SPEGMA 1100) leads to the separation of monomer and inhibitor. In addition, it is especially it is important to replenish dissolved oxygen after melting the drum material before use. Dissolved Oxygen Replenishment and Mixing MEHQ's monomer can be made using a palette or a drum toggle switch. The melting process requires a temperature of 20 °C or higher, but not more than 35 °C as the heating temperature. Heating the product indoors at a temperature of 20-25 °C for several days is the preferred option. Alternatively, if faster melting is required, heating cabinets that use hot water or hot oil are the preferred device for defrosting Stearylpolyethyleneglycol Methacrylate 1100 (SPEGMA 1100), as this avoids hot spots. Local hot spots above 35 ° C can lead to premature aging of the material. Product temperatures above 45 °C may lead to the polymerization of the monomer. During storage in the form of molten liquid, it is advisable to replenish the content of dissolved oxygen weekly. Stearylpolyethyleneglycol Methacrylate 1100 (SPEGMA 1100) must contain a stabilizer and the storage temperature must not exceed 20 °C to prevent premature deterioration. If the above conditions are met, then during storage, you can expect the storage stability of Stearylpolyethyleneglycol Methacrylate 1100 (SPEGMA 1100) for 6 months.
