INTRODUCTION
Poly (butadiene)-Containing polymers are widely used to improve the viscoelastic properties of composed materials such as tires (1-3), engineering plastics (4), adhesives (5), (6), and modified asphalt (7). The poly (butadiene) microstructure (i.e., the relative number of its isomers: 1,4-cis, 1,4-trans, and 1,2-vinyl) has an important effect on both the properties of the polymers containing poly (butadiene) (8-10) and the interaction of such type of polymers with other constituents of composed materials (7), (9), (11). Depending on its 1,4-trans content, poly (butadiene) behaves like an elastomer (40-80%) or as a thermoplastic resin (> 90%) (12). It ...
