Preparation of poly:urethane foams in presence of hydrocarbon(s)

Preparation of poly:urethane foams in presence of hydrocarbon(s)

The process is by reacting an organic isocyanate with a polyester polyol in the presence of a 4-6C hydrocarbon - comprises reacting a mixture of polar and non-polar polyester polyols in the presence of heat, then reacting the solution with the isocyanate component in the presence of standard additiv...
