When Organic Polymers Meet Polysiloxanes: A Revolution in Performance Fusion

In the design of functional polymer materials, how can organic polymers be endowed with the flexibility, hydrophobicity, weather resistance, and biocompatibility of siloxanes? IOTA-611 Mono-Terminated Hydrogen Silicone Oil, as a reactive macromolecular monomer, builds a chemical bridge connecting organic polymers with polysiloxanes.

Core Functional Value

• Precise End-Group/Side-Chain Grafting
  Through hydrosilylation reactions, polydimethylsiloxane segments can be introduced into the end groups or side chains of polymers containing C=C or C≡C bonds, enabling directional functionalization of molecular structures.

• Modification of Surface and Bulk Properties
  Grafted polymers can simultaneously improve surface smoothness, wear resistance, breathability, and anti-stick properties while maintaining a balance in bulk mechanical performance.

• Balance of Compatibility and Reactivity
  Compatible with various hydrogen-containing silicone oils, suitable for silicone-based systems and extendable to modifications of organic polymers such as acrylates, polyolefins, and epoxies.

Overview of Physical and Chemical Properties

• Appearance: Colorless to light yellow transparent liquid

• Molecular Weight Range: 850–3000 Da (customizable)

• Viscosity: 5–40 mPa·s (25°C)

• PDI: <1.50, narrow molecular weight distribution

• Chloride Ion Content: <20 ppm, high purity

Application Field Examples

• Coatings and Inks: Grafting enhances coating smoothness, wear resistance, and anti-adhesion properties.

• Textile Finishing Agents: Imparts durable softness and hydrophobic effects to fibers.

• Biomedical Materials: Improves the biocompatibility and lubricity of polymer surfaces.

• Plastic Modification: Enhances the flexibility, scratch resistance, and surface gloss of engineering plastics.

Process Integration Recommendations

1. Direct Addition Method: Participates as a macromonomer in the copolymerization of unsaturated polymers.

2. Post-Functionalization Method: Performs hydrosilylation grafting modifications on synthesized polymers.

3. Compounding Use: Works synergistically with di-functional hydrogen-containing silicone oils to control grafting density and segment distribution.

Storage, Transportation, and Safety

• Packaging Options: Various specifications from 1 kg to 200 kg, nitrogen-purged to prevent oxidation.

• Storage Requirements: Store in a cool, dry place away from light, acids, bases, and oxidizers.

• Usage Tips: Operate under an inert atmosphere to avoid contamination by moisture and catalyst poisons.
