FOAM-FORMING COMPOSITIONS CONTAINING AZEOTROPIC OR AZEOTROPE-LIKE MIXTURES CONTAINING Z-1,1,1,4,4,4-HEXAFLUORO-2-BUTENE AND THEIR USES IN THE PREPARATION OF POLYISOCYANATE-BSED FOAMS |
摘要 |
Foam-forming compositions containing azeotropic or azeotrope-like mixtures containing cis-1,1,1,4,4,4-hexafluoro-2-butene are disclosed. The foam-forming composition contains (a) an azeotropic or azeotrope-like mixture of cis-1,1,1,4,4,4-hexafluoro-2-butene and dimethoxymethane; and (b) an active hydrogencontaining compound having two or more active hydrogens. Also disclosed is a closed-cell polyurethane or polyisocyanurate polymer foam prepared from reaction of an effective amount of the foam-forming composition with a suitable polyisocyanate. Also disclosed is a process for producing a closed-cell polyurethane or polyisocyanurate polymer foam by reacting an effective amount of the foam-forming composition with a suitable polyisocyanate. |
