1,3-Butadiene (CH₂=CH-CH=CH₂) is the central monomer of synthetic rubber, with global production of around 12 million tonnes annually. Its conjugated diene structure enables 1,4- and 1,2-addition, producing the cis-1,4, trans-1,4, and 1,2-vinyl microstructures that give synthetic rubbers their elasticity. The father of SBR, BR, and NBR — but classified as IARC Group 1 carcinogen, with occupational exposure linked to leukemia.

Market Trends & Notes
ナフサ価格・原油価格・タイヤ需要に強く連動。SBR/BR需給がタイヤ生産量で大きく振れるため、スポット変動が大きい。アジア(中国・韓国・日本)が世界最大の生産・消費地、北米はETC原料移行でC4副生減少のため近年タイト
