摘要：Improved low temperature properties of polyureaurethane are obtained, suchas low glass transition temperatures and reduced bending moduli at -40°C, by the use ofrelatively high molecular weight polyether polyol intermediates. The polyureaurethane ismade by reacting the polyether polyol intermediate with a diisocyanate and subsequentcure with a metal halide salt complex of methylenedianiline.
