Description

Polystyrene A-Br CAS NO 107175-46-2 is a brominated polystyrene derivative, specifically an atom transfer radical polymerization (ATRP) initiator or functionalized polymer intermediate. This compound is critical for the controlled synthesis of well-defined block copolymers and functional materials with precise molecular architectures. It is essential for researchers and manufacturers in advanced polymer science, particularly for developing specialty coatings, adhesives, and high-performance thermoplastic elastomers.

Application

• As a macro-initiator for the synthesis of block copolymers via controlled radical polymerization techniques like ATRP.
• Production of functionalized polymer brushes and surfaces for advanced coating applications.
• Manufacturing of compatibilizers and impact modifiers for polymer blends and composites.
• Research and development of novel thermoplastic elastomers with tailored properties.
• Creation of specialized resins for adhesives, sealants, and encapsulants.
• Development of polymeric materials for biomedical and pharmaceutical applications.
• Precursor for generating complex polymer architectures such as stars, grafts, and networks.
