Crystallization and melting of filled 1,4-cis-polybutadiene

Crystallization behavior of polybutadiene containing silica particles

“…Since first synthesized in 1910, poly(butadiene) has attracted the attention of many researchers because of the low glass‐to‐rubber transition temperature ( T g ). Because of its semicrystalline nature, various researches1–18 have been carried out to clarify the crystalline structure and crystallization kinetic. Natta et al4 revealed that there are four possible stereoisomers of poly(butadiene), which can be controlled by the catalyst type and the mechanism of polymerization reaction.…”

“…The experimental results were theoretically discussed by two asymptotic crystallization theories including equilibrium theory of crystallization in a phantom network and kinetic theory of nucleation in a system of asymmetric elements 12. The nucleating ability by other materials such as carbon blacks14 and clays15 have been also studied. Peterman et al16 found that BR epitaxially crystallizes on polypropylene substrates.…”
