The water-resistant behavior and the mechanical properties of the PUU films consisting of POA were enhanced appreciably resulting from the strong hydrogen bonding in urea carbonyl groups in the hard segments.

The samples were stored at refrigerated temperature (4[degrees]C [+ or -] 1[degrees]C) and analysed at three day interval for various parameters (pH, colour and odour score, peroxide, thiobarbituric acid reacting substances [TBARS], total carbonyl contents and total plate count) up to 9 days.
