Damping materials based on liquid poly(butadienes): Structure-property relationships

Liquid poly(butadiene) resins can be defined as oligomers with a degree of polymerization (Dp) of 100 and molecular weights below the critical molecular weight. These materials have rheology defined as viscous flow at temperatures of less than 60°C. In this regime, properties such as glass transition temperature and viscosity are determined by both microstructure and macrostructure. In applications such as adhesives, thermoplastic modification or tire compounding, liquid poly(butadienes) are often used as high value additives, imparting specific performance enhancement
