Polybutadiene with predominantly 1,2-addition is widely used in the production of high-impact polystyrene (HIPS) and acrylonitrile-butadiene-styrene (ABS) resins. Its excellent compatibility with styrene enhances the toughness and impact resistance of these materials, making them suitable for automotive parts, electronic housings, and consumer goods. Additionally, it serves as a key component in adhesives and sealants, providing flexibility and strong bonding properties. In the tire industry, it improves the abrasion resistance and durability of rubber compounds. Its unique structure also makes it valuable in modifying asphalt for road construction, enhancing elasticity and reducing cracking.
