The water-resistance properties of polyester-based polyurethanes are remarkably enhanced, without adversely affecting the transparency properties of these materials to any significant degree, by including in the polymer a substantially dispersed nano-particle proton scavenger. The hydrolytic stability and water-resistance properties of polyester-based polyurethanes are remarkably enhanced and match those of polycarbonate-based polyurethanes, without adversely affecting the transparency of these materials to any significant degree, by including in the polymer a substantially dispesed nano-particle proton scavenger such as calcium carbonate.
