What is POLYPROPYLENE, CHLORINATED

**Introduction to Chlorinated Polypropylene (CPP)** Chlorinated Polypropylene (CPP) is a modified thermoplastic polymer created by introducing chlorine atoms into the polypropylene (PP) chain. This chlorination process enhances properties such as chemical resistance, adhesion, and flame retardancy while retaining PP’s lightweight and durable characteristics. CPP is widely used as a binder or coating in adhesives, inks, and paints, particularly for polyolefin substrates where standard coatings struggle to adhere. It also finds applications in automotive parts, packaging films, and corrosion-resistant coatings. With excellent solubility in organic solvents and improved compatibility with polar materials, CPP offers versatility for industrial and specialty applications. Its balance of performance and processability makes it a valuable material in demanding environments.

Preparation Process: **Preparation Method of Chlorinated Polypropylene (CPP):** 1. **Dissolution:** Dissolve polypropylene (PP) in a chlorinated hydrocarbon solvent (e.g., carbon tetrachloride) at 60–100°C under nitrogen. 2. **Chlorination:** Introduce chlorine gas (Cl₂) into the solution under UV light or with a radical initiator (e.g., azobisisobutyronitrile, AIBN) at 70–120°C. 3. **Control:** Monitor chlorine content (typically 20–65 wt%) by adjusting reaction time, temperature, and Cl₂ flow rate. 4. **Neutralization:** Add aqueous sodium hydroxide (NaOH) to remove residual HCl. 5. **Precipitation:** Pour the mixture into methanol to precipitate CPP. 6. **Washing & Drying:** Wash the solid with water and dry under vacuum at 50–80°C. (100 words)

Usage Scenarios: Chlorinated polypropylene (CPP) is primarily used as an adhesive and coating material due to its excellent chemical resistance, adhesion properties, and compatibility with various substrates. It enhances the bonding of inks, paints, and primers to polypropylene and other difficult-to-adhere plastics in automotive, packaging, and industrial applications. CPP is also employed as a modifier in coatings to improve flexibility, durability, and moisture resistance. Additionally, it serves as a flame retardant and impact modifier in certain plastic formulations. Its chlorine content provides enhanced thermal stability and UV resistance, making it suitable for outdoor applications such as protective films and weather-resistant coatings.
