Influences of Soft Monomers on the Application Properties of Hydrophilic Polyurethane with Mixed Polyether Segment

Article Preview

A series of hydrophilic polyether polyurethanes were prepared with two-steps technique from 4,4’- diphenylmethane diisocyanate (MDI), polytetramethylene glycol 1000 (PTMG1000) and polyethylene glycol 1000 (PEG1000) with 1,4-butanediol (BDO) as the chain extender. Further more, the relationships between structure and moisture permeability, water resistance, hydrophility and phase inversion temperature (PIT) of the polyurethanes was investigated. For polyether polyurethanes with nicer micro phase separation structure, the studies show that the hydrophilic ether bond content and mobility of soft segment chains have decisive effect on their water resistance, moisture permeability and hydrophility without reference to the soft segment content on the whole.
