Poly(α-methylstyrene) is a specialty thermoplastic resin characterized by its high glass transition temperature (around 170°C) and excellent thermal stability. It is primarily used as a performance modifier in adhesives, coatings, and inks to improve heat resistance, adhesion, and mechanical properties. Commonly applied in automotive coatings, electronic encapsulants, and high-performance structural adhesives. Its good solubility in organic solvents facilitates processing, and it forms transparent, hard films ideal for applications requiring durability, clarity, and low residue. The softening point ranges from 85-145°C, making it suitable for heat-intensive processes.
