Stearyl methacrylate

Description:

Stearyl methacrylate is an organic compound classified as a methacrylate ester, characterized by its long hydrophobic stearyl chain and a methacrylate functional group. It is typically a colorless to pale yellow liquid with a mild odor. The compound is known for its low volatility and relatively high viscosity, which can vary depending on temperature. Stearyl methacrylate is soluble in organic solvents such as ethanol and acetone but has limited solubility in water due to its hydrophobic nature. This substance is primarily used in the production of polymers and copolymers, contributing to the formulation of coatings, adhesives, and sealants that require enhanced water resistance and flexibility. Additionally, it can improve the thermal stability and mechanical properties of materials. Safety data indicates that while it may cause irritation upon contact with skin or eyes, proper handling and safety precautions can mitigate risks. Overall, stearyl methacrylate is valued in various industrial applications for its unique properties and versatility.

Octadecyl Methacrylate

CAS: 32360-05-7

Octadecyl methacrylate is a monomer that polymerizes to form poly(octadecyl methacrylate) (POM), a high-resistance, hydrophobic polymer. POM is synthesized by free-radical polymerization of octadecyl methacrylate in the presence of oxygen and heat. The copolymerization reaction mechanism is initiated by the abstraction of an electron from one of the monomers by the other, leading to radical formation. Radical-initiated reactions are often terminated by hydrogen bonding between radicals on adjacent chains. These intermolecular hydrogen bonds are responsible for the high resistance and hydrophobic properties of POM.
Octadecyl methacrylate can be used as a sealant for water vapor because it has a low permeability for water vapor due to its hydrophobic properties. It also has potential use as a model system for acrylates and other reactive monomers, due to its high resistance to
