ABSTRACT:
The present invention is an optically clear impact resistant polyurethane which provides exceptionally high heat distortion temperatures and excellent chemical resistance. The invention is particularly useful for transparency applications that require excellent impact resistance coupled with high heat distortion temperatures, such as glazings for buildings, vehicles, riot shields, aircraft canopies, and face masks.
