Isotactic specific catalyst for direct production of highly isotactic poly (propylene oxide) or highly isotactic poly (butylene oxide)
摘要:
(Salph or methoxy salph) Co (initiating ligand) catalyze homopolymerizing rac-PO to produce pure highly isotactic PPO and rac-1-butylene oxide to produce pure isotactic poly(butylene oxide). A product is unfractionated isotactic PPO of m-dyad content >81%, normally at least 99%.
