Polyether macromonomers (PEMs) are reactive oligomers with terminal functional groups, widely used as key intermediates in polymer synthesis. Their structure typically combines a polyether backbone (e.g., polyethylene glycol or polypropylene glycol) with polymerizable end groups such as methacrylate or vinyl.
Production & Applications
PEMs are synthesized via anionic ring-opening polymerization of epoxides, followed by end-capping with functional monomers. This process allows precise control over molecular weight and functionality. Major applications include:
Concrete admixtures: PEMs improve fluidity in polycarboxylate superplasticizers.
Hydrogels: Used in biomedical devices due to tunable hydrophilicity.
Coatings: Enhance flexibility and adhesion in UV-curable resins.
Market Trends
The global PEM market is projected to grow at 6.2% CAGR (2023–2030), driven by infrastructure development in Asia-Pacific. Challenges include raw material price volatility and regulatory pressure on ethylene oxide derivatives.
