	%X Polyurethane foam (PUF) were prepared by
reacting polyols synthesized from soy-oil into mixture of 2,4-
Toluene diisocyanate (TDI) with 4,4--Methylene Diamine
Isocyanate (MDI) with ratio of 70:30. The polyols obtained
via esterification reaction were categorize into different
temperature of reaction and by used of varied concentration
of phosphoric acid catalyst. The purpose of catalysts is to
shifting selectivity to a desired and value added of product.
The effect of stoichiometric balance (molar ratio of
epoxide/ethylene glycol) to the concentration of the catalyst
on the final properties was evaluated.
