Allyloxypolyethyleneglycol(APEG) CAS 27274-31-3
APEG
Allyloxypolyethyleneglycol (APEG) is a non-ionic, bifunctional polyether that combines a hydrophilic polyethylene-glycol (PEG) backbone with a terminal allyl ether group. This product is soluble in water and various organic solvents. It is an important raw material for the new generation of polycarboxylic acid-based high-efficiency water-reducing agents. Polycarboxylic acid-based high-efficiency water-reducing agents synthesized using this raw material have excellent particle dispersion and retention properties, with advantages such as high water-reduction rate, low cement consumption, good strengthening effect, good durability, no rusting of steel bars, and environmental friendliness. It can be applied to high-performance, high-strength (C60 and above) commercial concrete for on-site mixing and long-distance transportation.

product superiority
1. Strong reaction compatibility——The molecular structure contains hydroxyl groups and double bonds. It can be used as a copolymerizing monomer to synthesize various functional polymers, and can also be used as a modification intermediate to improve the structure of organic silicon and other materials.
2. Excellent environmental protection performance——Compared to traditional monomer acrylate, it has less irritation when used, and is more friendly to operators and the environment. Additionally, as an environmentally friendly monomer, it can reduce the generation of pollutants during the production process.
3. Moderate polymerization activity——The allyl double bond free radical polymerization has moderate activity, is not prone to self-polymerization, and has good storage stability. The molecular weight is controllable, with a molecular weight range of 400-2400 that can be adjusted, and it can be customized for the synthesis of different performance water reducers.
application scenarios
1. Water reducer raw materials——Mainly used for the production of polycarboxylic high-efficiency water reducers, suitable for on-site mixing and long-distance transportation of high-performance concrete (with strength above C60).
2. In the field of coatings and resins——It is an important copolymerizing monomer for fluorocarbon resins. When added, it can adjust the hardness of the coating film and also endows the fluorocarbon resin with hydrophilicity, thereby optimizing the performance of fluorocarbon coatings.
3. In the field of ceramics and material processing——It is used as a water-reducing agent raw material in ceramic production, which can significantly improve the gelation performance of ceramic slurry, making the slurry more uniformly dispersed.
