Clear microemulsions can allegedly be formed spontaneously by combining water; a volatile siloxane, a long chain or high molecular weight silicone poly ether (such as DC 5329 as a high molecular weight silicone polyether and DC 5211 as a low molecular weight polyether from Dow Corning) and, optionally a cosurfactant such as a monohydroxy alcohol, organic diol, organic triol
, organic tetraol, silicone diol, silicone triol
, silicone tetraol and a nonionic organic surfactant.
00 experimental polyol is a triol
, or three-functional product, designed for blending with other polyols and targeted to rigid foam applications.
Tenders are invited for Supply of Ote 126 hexane triol

The solid was washed with absolute EtOH and dried in vacuo to give 90% of the hygroscopic triol
(Adm), as a white solid with mp = 160[degrees]C.

A resin reactor equipped with thermometer, mechanical stirrer, Dean-Stark apparatus, and nitrogen inlet was charged with diacid, diol, and triol
in the mole ratio of 0.
For poly(lactide) triol
and PCL diol synthesis, glycerol and 1,4-butane diol were used as D,L-lactide and [epsilon]-caprolactone polymerization initiators.

In the previous experiments we had used a poly-caprolactone triol
as the organic polyol in the siloxane-polyurethane coating system.

The higher the content of soft foam in the composition the higher the amount of high molecular weight polyether triol
, but at the same time also that of polyureas resulting from the polyisocyanate-water reaction during soft foam production.
A 6,200 mw propylene oxide triol
synthesized through KOH catalysis (with a small ethylene oxide cap for reactivity) will contain between 40-45% monol content on a molar basis.
