Process for preparing cellular polyurethane elastomers based on 3,3'-dimethoxy-4,4'diisocyanato-diphenyl and/or 4,4'-stilbene-diisocyanate |
摘要 |
A process is disclosed for preparing microcellular polyurethane elastomers by reacting: (a) high-molecular polyhydroxyl compounds, optionally (b) low-molecular chain-lengthening and/or cross-linking agents with (c) 3,3'-dimethoxy-4,4'-diisocyanato-diphenyl and/or 4,4'-stilbene-diisocyanate in the presence or absence of (d) catalysts; (e) foaming agents; and (f) additives. Also disclosed are isocyanate prepolymers suitable for preparing these elastomers. |
