PROCESS FOR THE PREPARATION OF CELLULAR AND NON- CELLULAR POLYURETHANE ELASTOMERS |
摘要 |
<p>For the preparation of optionally cellular and non-cellular polyurethane elastomers, preferably by reaction injection molding, organic polyisocyanates, polyether polyols based on polyoxyalkylene polyether polyols with terminal hydroxyethylene groups and an ethoxylation degree of 1 to 13, having a content of primary hydroxyl groups at the corresponding degree of ethoxylation as the value of curve A to 100 percent with curve A describing the dependency of the primary hydroxyl group content upon the degree of ethoxylation are reacted with chain extenders and/or cross-linking agents in the presence of catalysts as well as optionally blowing agents, auxiliaries and additives.</p> |
