(d) JEFFOL ® SG-360 polyol from <strong>Huntsman</strong>: A sucrose and glycer<strong>in</strong> co-<strong>in</strong>itiated polypropylene oxide extended<br />
polyether polyol which represents bio-renewable content polyol <strong>in</strong> use by the polyurethane <strong>in</strong>dustry for decades. The biorenewable<br />
content of this polyol is significantly lower, 24%, compared to AGROL ® Diamond polyol, but its functionality<br />
and hydroxyl number is high and it too does not conta<strong>in</strong> any aromatic groups. Thus, it was evaluated as a physical blend<br />
with STEPANPOL ® PS-2352, an aromatic polyester polyol.<br />
