ABSTRACT:
Polyurethane, polyisocyanurate and polyurea polymers, particularly foamed polymers can be prepared from formulations including non-silicone polyether surfactants. The non-silicone polyether surfactants can be polyethers having from about 10 to about 90 weight percent oxyethylene units and from about 10 to about 90 weight percent oxyalkylene units having at least 4 carbons. The non-silicone polyether surfactants can be used to prepare foams having properties substantially similar to foams prepared with conventional silicone based surfactants.
