| 摘要 |
This invention relates to reaction injection molded elastomers derived from high molecular weight amine terminated polyethers and/or high molecular weight polyols, a chain extender, a polyisocyanate, a chloro and/or isocyanate silane coupling agent, and untreated filler material. The reaction injection molded (RIM) elastomers of this invention are useful, for example, as automobile body parts.
