Abstract
AbstractTransition metal–catalyzed polymerization of 1,3‐butadiene obtained from the erythritol, a kind of biomass product, was investigated to evaluate the effect of byproducts in the synthesis of 1,3‐butadiene from erythritol. Nuclear magnetic resonance spectroscopy and size exclusion chromatography results show that cis‐1,4‐polybutadiene can be selectively obtained using biomass 1,3‐butadiene model gas, which contains 1‐butene, cis‐2‐butene, and trans‐2‐butene, or erythritol‐derived 1,3‐butadiene, and no effect of butenes on the conversion rate or the microstructure of the resulting polymer was observed compared with using naphtha‐derived 1,3‐butadiene. The vulcanizate of the cis‐1,4‐polybutadiene obtained using 1,3‐butadiene having a biomass model gas containing butenes has mechanical properties equivalent to those of naphtha‐derived polybutadiene in tensile tests. This demonstrates that erythritol can be used as a new raw material for cis‐1,4‐polybutadiene.
