SINOMER® MPEGMA 350

(Water-Soluble Reactive Monomer with High Wetting & Flexibility)

Chemical Name:  Poly(ethylene glycol) (350) methyl ether methacrylate

CAS No.:    26915-72-0

Molecular structure:

General information :

SINOMER® MPEGMA 350 is a long-chain methacrylate monoester based on an ethylene oxide backbone, containing approximately 8 ethylene oxide (EO) units . This functional monomer combines a polymerizable methacrylate group with a hydrophilic PEG chain, offering excellent water solubility and compatibility with various resin systems. It is manufactured using advanced esterification technology to achieve high esterification rate (≥93%) and low residual acid content , ensuring consistent performance in demanding applications.

技术指标 :
检验项目 (Item) 指标要求 (Specification)
Appearance (RT) Slightly yellow transparent liquid
色度 (APHA) ≤ 50
Viscosity (cps @ 25°C) 15 - 45
Acid Value (mg KOH/g) ≤ 1.0
Water Content (wt%) ≤ 0.2
性能特点 :
  • High wetting ability – PEG chain provides excellent substrate wetting and penetration

  • Water soluble – Imparts water solubility or dispersibility to non-ionic organic molecules

  • Flexibilizing effect – Low glass transition temperature (Tg) enhances flexibility and reduces brittleness in cured films

  • Reactive monomer – Methacrylate group enables copolymerization with acrylic, urethane, and other vinyl systems

  • Low residual acid – Minimizes side reactions and ensures formulation stability
