Synthesis of poly (hydroxyurethane)s from bis(cyclic carbonate) and diamine

摘要

In the present study, the synthetic procedure of poly (hydroxyurethane) from diglycidyl ether and carbon dioxide was investigated. Among quaternary ammonium salts tested, the one having larger alkyl group and more nucleophilic counter anion exhibited a better yield of bis (cyclic carbonate). Poly(hydroxyurethane) was prepared by polyaddition of bis(cyclic carbonate) and diamine. Due to the stiffness of aromatic chain, the poly(hydroxyurethane) having aromatic chain showed higher thermal stability than the polymer of aliphatic chain. Poly (hydroxyurethane) showed higher thermal stability and higher resistance to solvent than model polyurethane did.
