Title:
脂肪族ポリカーボネートクエンチ方法
Document Type and Number:
Japanese Patent JP5748662
Kind Code:
B2
Abstract:
The present disclosure is directed to, in part, an aliphatic polycarbonate polymerization reaction initiated by combining an epoxide with carbon dioxide in the presence of a catalytic transition metal-ligand complex to form a reaction mixture, and further quenching that polymerization reaction by contacting the reaction mixture with an acid containing a non-nucleophilic anion produces a crude polymer solution with improved stability and processability.
