Abstract
Official abstract text for this publication.
This invention relates to compositions comprising 1,2-dichloro-1,2-difluoroethylene (i.e., CFO-1112) and an additional component. The compositions described herein may be useful, for example, in foam blowing applications.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for preparing a thermoset polymer foam, the process comprising reacting a foamable composition comprising a polyol, an isocyanate, and a blowing agent under conditions effective to form the thermoset polymer foam, wherein the blowing agent comprises: i) 21.3 wt % to 70.8 wt % of 1,2-dichloro-1,2-difluoroethylene, and ii) 78.7 wt % to 29.2 wt % of one or more compounds selected from HFO-1336mzz-E and HFO-1336mzz-Z. 2. The process of claim 1 , wherein the foam is a spray foam. 3. The process of claim 1 , wherein the foamable composition further comprises one or more additional components selected from at least one catalyst, at least one surfactant, water, at least one flame retardant agent, and at least one nucleating agent. 4. The process of claim 3 , wherein the polyol is a polyester polyol. 5. The process of claim 1 , wherein the foamable composition comprises at least one catalyst. 6. The process of claim 1 , wherein the foamable composition comprises a surfactant. 7. The process of claim 1 , wherein the foamable composition comprises a flame retardant agent. 8. The process of claim 1 , wherein the foamable composition comprises a nucleating agent. 9. The process of claim 1 , wherein the foam is a polyurethane foam or a polyisocyanurate foam. 10. The process of claim 1 , wherein the blowing agent comprises 1,2-dichloro-1,2-difluoroethylene and HFO-1336mzz-Z. 11. The process of claim 1 , wherein the blowing agent comprises 1,2-dichloro-1,2-difluoroethylene and HFO-1336mzz-E.
