Study on the Micro-Phase Structure of Hydrophilic Polyurethane with Mixed Polyester and Polyether Soft Segments

Abstract:

Polyether-polyester nonionic hydrophilic polyurethanes with amorphous soft segment phase are prepared from 4,4’- diphenylmethane diisocyanate (MDI), polybutylene adipate glycol 2000 (PBA2000) and polyethylene glycol 1000 (PEG1000) with 1,4-butanediol (BDO) as chain extender. Further more, the relationships between micro-phase structure and chemical structure of samples is investigated. The studies show that the chemical structure has remarkable effects on the micro-phase structure of hydrophilic polyurethane and micro-phase separation degree of the mixed soft domains.
