Macromonomer SINTEPEG 2400

(registered trade name) Chemical name: Methyl polyethylene glycol, polyethylene glycol monomethyl ether; IUPAC chemical name: Alpha-2-Methylpro-2-enyl-omega-hydroxypoly (hydroxy-1,2-ethandyol); Common designations: APEG 2400, HPEG 2400, SPEG 2400; SINTEPEG 2400

Methallylpolyethylene glycol SINTEPEG is a high-molecular-weight, water-soluble non-ionic monomer with a molecular weight of 2400, obtained by ethoxylation of metallyl alcohol.

It is produced in two product forms:
  • Scaled powder;
  • 60% aqueous solution;

SINTEPEG 2400 application:

Scope of use "SINTEPEG" 2400 - as an initial macromonomer for the polycarboxylate ethers synthesis.

  • Application
  • Specification

The flake form of SINTEPEG 2400 is packaged in big bags with polyethylene liner with a net weight of 750 kg; An aqueous solution of SINTEPEG 2400/60 is poured into:
- polyethylene barrels with a capacity of 227 liters;
- IBC containers, 1000 liters;

The warranty period for the SINTEPEG 2400 is 1 year from the date of manufacture.
To prevent polymerization and clumping, the SINTEPEG 2400 macromonomer is recommended to be stored at a temperature not higher than + 30 ° C. The lower limit of temperature is not specified. To prevent crystal formation and polymerization, SINTEPEG 2400/60 macromonomer should be stored at a temperature of 10 to 30 ° C. As a result of long-term storage at lower temperatures, precipitation may occur in the SINTEPEG 2400/60. The product does not lose its quality, but before use it is need to be heated to a temperature of 20-30 ° C and homogenized.
