摘要:
Melt processable polyurethaneureas are prepared from a diisocyanate, a macroglycol, a diol chain extender and a diamine chain extender. Water may be included as a reactant, and the polymer may contain an additive such as a radiopaque material. The invention includes a one-pot bulk polymerization method for preparation of the polymers.
