HP-POL PDA Polyethylene Glycol Di(meth)acrylate
Abstract
The HP-POL PDA series is polyethylene glycol di(meth)acrylate (PEGDA/PEGDMA), a functional monomer with polymerizable double bonds at both ends of the molecule. Combining the hydrophilicity and flexibility of the polyethylene glycol (PEG) segment with the high reactivity of the (meth)acrylate groups, it is a key synthetic raw material for high-performance superplasticizers, coating dispersants and photocurable 3D printing materials. The unsaturated double bonds in the molecule efficiently participate in free-radical polymerization (thermally or photo initiated), imparting excellent properties to the polymer network.

Product Selection Guide
- HP-POL PEG-6DA / PEG-6DMA (molecular weight ~400): Provides higher crosslink density and reaction rate, suitable for fast-curing systems with lower flexibility requirements and for the synthesis of high-efficiency superplasticizers.
- HP-POL PEG-11DA / PEG-11DMA (molecular weight ~615): Provides a longer flexible PEG segment, imparting better flexibility, hydrophilicity and greater steric hindrance, especially suitable for preparing hydrogels and high-performance dispersants with special mechanical property requirements.
Main Application Fields
- High-performance polycarboxylate superplasticizer (PCE): As a core functional monomer, participates in copolymerization to synthesize comb-structured polycarboxylate superplasticizers. The PEG segment provides excellent water solubility and steric hindrance, while the terminal (meth)acryloyl groups ensure firm grafting onto the polymer backbone, imparting high water reduction, excellent slump retention and good adaptability to concrete.
- Coating and ink dispersants: As a key intermediate or comonomer for synthesizing polymer dispersants, copolymerized with monomers such as styrene-maleic anhydride and acrylates to prepare high-performance waterborne dispersants for titanium dioxide, carbon black and various organic pigments, significantly improving pigment wetting, reducing grinding viscosity and enhancing storage stability.
- Photocurable 3D printing polymers: An ideal photosensitive prepolymer or crosslinker for photocurable 3D printing, especially hydrogel printing in the biomedical field. With the good biocompatibility of the PEG segment, it is widely used as a “bio-ink” for 3D printing of cell culture scaffolds, tissue engineering materials and drug delivery carriers; the di(meth)acrylate functionality ensures rapid photopolymerization, suitable for high-precision 3D printing technologies such as DLP and SLA.
- Other polymer modification: As a crosslinker or functional monomer for UV-curable coatings, inks and adhesives, polymer electrolytes, textile printing and dyeing auxiliaries, and paper chemicals.
