摘要：
The effect of shock block sequence distribution on surface morphology and wetting behavior was analyzed. It was observed that polyurethanes such as PU-1 were highly effective in modification of the surface of conventional polyurethanes. It was also observed that the polyurethanes were prepared using polyoxetane telechelics or a reference PTMO soft segment. It was found that polyurethanes had different nanoscale morphologies and water contact angle was dependent on soft segment sequence.
