Характеристики

Ключевые свойства и преимущества

Enhanced Hydrophobicity: Provides excellent water and moisture resistance to copolymers due to its long alkyl chain structure and non-polar nature.
Internal Plasticization: Effectively lowers the glass transition temperature of polymer matrices, eliminating the need for adding potentially migratory external plasticizing agents.
Weathering Durability: Offers exceptional resistance against UV degradation and atmospheric oxidation, maintaining structural integrity and surface appearance in outdoor settings.
Low Volatility: High boiling point ensures minimal evaporation during radical polymerization processes and high-temperature industrial applications or curing cycles.
Broad Compatibility: Easily undergoes free-radical copolymerization with various acrylic, methacrylic, and vinyl monomers to customize mechanical and chemical properties.

Спецификации

Технические особенности

Molecular Formula and Mass: C12H22O2 with a molar mass of approximately 198.30 g/mol, which is essential for precise high-purity laboratory synthesis.
Glass Transition Temperature (Tg): The resulting homopolymer displays a Tg of approximately -10°C, providing the necessary soft segment flexibility and low-temperature performance.
Density and Refractive Index: Specific gravity is recorded as 0.885 g/cm³ at 20°C, and the refractive index typically measures at a value of 1.439.
Flash Point and Boiling Point: The boiling point is 214°C at 760 mmHg, while the flash point is approximately 92°C, requiring specific safety protocols.
Inhibitor Specification: Usually stabilized with Hydroquinone Monomethyl Ether (MEHQ) at 10-100 ppm to prevent premature polymerization during storage and transport.
