SPECIFIC COMPOUNDS - The compound (I) is tetrafluoropropenes (HFO-1234), preferably cis- and trans-HFO-1234ze (1,1,1,3-tetrafluoropropene); or trifluoromonochloropropenes (HFCO-1233), e.g. HFCO-1233xf (1,1,1-trifluoro-2-chloropropene) or HFCO-1233zd (cis- and trans-1,1,1-trifluoro-3-chloropropene).    EXAMPLE - A gaseous blowing agent combination was formed comprising HFO-1234ze ( approximately 60 mol%), and cyclopentane ( approximately 40 mol%). A polyurethane foam was prepared using the above blowing agent combination. Comparative foams were also made using a blowing agent consisting of HFC-245fa and a blowing agent consisting of cyclopentane. The prepared foams were evaluated for k-factor and compressive strength. The % yields in the parallel direction were 13.513, 13.881 and 11.462 for HFO-1234e/cyclopentane, HFC-254fa and cyclopentane, respectively. The k-factors, at mean temperature of 40 degrees F, were 0.127, 0.146 and 0.143 BTU in/hr ft 2 degrees F for HFO-1234e/cyclopentane, HFC-254fa and cyclopentane, respectively.
