摘要：

Micro-phase separation in hexamethylynediisocyanate-polyurea was studied using small-angle X-ray scattering and infrared absorption. It was found that phase separation in this system followed spinodal-like decomposition on a 3-4 nm size scale with phase separation occuring on a time scale of days.
