IMPACT RESISTANT POLYURETHANE AND POLY(UREAURETHANE) ARTICLES AND METHODS OF MAKING THE SAME

摘要

The present invention provides polyurethane materials including a first portion of crystalline particles having self-orientation and bonded together to fix their orientation along a first crystallographic direction and a second portion of crystalline particles having self-orientation and bonded together to fix their orientation along a second crystallographic direction, the first crystallographic direction being different from the second crystallographic direction, wherein said crystalline particles comprise greater than about 30% of the total volume of the polyurethane material; compositions, coatings and articles made therefrom and methods of making the same.
