Abstract
Improved low temperature properties of polyureaurethane are obtained, such as low glass transition temperatures and reduced bending moduli at -400.degree. C., by the use of relatively high moleuclar weight polyether polyol intermediates. The polyureaurethane is made by reacting the polyether polyol intermediate with a diisocyanate and subsequent cure with a metal halide salt complex of methylenedianiline.
