Processability of hydrocarbon blown, polyisocyanate based foams through
use of a compatibilizing agent
摘要:
There is now provided a polyisocyanate-based foam made by an organic polyisocyanate with a polyol solution containing a C.sub.4 -C.sub.7 aliphatic and/or cycloaliphatic hydrocarbon as a blowing agent. The hydrocarbon blowing agent is soluble in the polyol solution having polyols with polyester linkages by using a reacted or unreacted compatibilizing agent represented by the formula: ##STR1## wherein R.sup.1 is preferentially OH, and R.sup.2 is a C.sub.6 -C.sub.24 aliphatic, branched or unbranched, hydrocarbon group.
