For Research and Development scientists in the chemical industry, a thorough understanding of raw material properties is fundamental to successful formulation and innovation. 4-Acryloylmorpholine (ACMO), a versatile functional monomer with CAS No. 5117-12-4, offers a unique set of chemical and physical attributes that make it highly valuable for advanced applications, particularly in UV-curable systems. As a dedicated manufacturer and supplier, we aim to provide comprehensive technical information on ACMO to empower scientists in their work. If you are considering using ACMO in your R&D projects, understanding these properties is key.

ACMO is characterized by its appearance as a colorless to pale yellow clear liquid. This physical state, combined with its low viscosity (typically 8-12 cps at 25°C), makes it an excellent reactive diluent. In UV-curable formulations, controlling viscosity is crucial for application methods, whether it's inkjet printing, spray coating, or dip coating. ACMO's low viscosity allows formulators to achieve target application viscosities, improving processability and enabling higher solids content, which can reduce VOC emissions.

Chemically, ACMO is a monofunctional monomer containing an acryloyl group and a morpholine ring. The acryloyl group is highly reactive under UV initiation, leading to rapid polymerization. This is the cornerstone of its fast-curing performance. The morpholine ring, on the other hand, imparts certain polarity and hydrophilicity, making ACMO miscible with water and many organic solvents. This solubility profile is advantageous, allowing its use in both solvent-borne and waterborne UV-curable systems, expanding formulation possibilities for R&D scientists.

Furthermore, ACMO exhibits a favorable toxicological profile. It is known for its low skin irritation and low odor, which are significant considerations for R&D scientists tasked with evaluating material safety and developing user-friendly products. This reduced hazard profile simplifies handling procedures and broadens the potential applications, including those where end-user contact is a possibility, albeit with appropriate regulatory compliance. The density of ACMO is approximately 1.122 g/cm³ at 25°C, a standard parameter for formulation calculations.

The glass transition temperature (Tg) of ACMO's homopolymer is around 145°C, indicating that it can contribute to cured materials with good thermal stability and hardness. However, as a monofunctional monomer, it also offers flexibility. When copolymerized with other monomers or oligomers, ACMO allows for the fine-tuning of mechanical properties, enabling formulators to achieve a balance between hardness, toughness, and flexibility – a critical aspect for performance optimization in advanced materials. For scientists seeking to buy ACMO for experimental purposes, understanding these property interactions is key to unlocking its full potential.

In summary, the properties of ACMO – its low viscosity, high reactivity, water miscibility, low odor, minimal irritation, and contribution to thermal stability and flexibility – make it an indispensable tool for R&D scientists developing innovative UV-curable products.
