摘要:
This invention relates to polyisocyanate-based polymers prepared by reacting a polyisocyanate with a polyol composition containing a polyester polyol and a poly(alkylene carbonate) polyol. The presence of the poly(alkylene carbonate) polyol improves the semi-conductive properties of the polymer without requiring the use of semi-conductive fillers or ionizable salts.
