Abstract: The invention disclosed is for novel polyols and a method of making said polyols which comprises interconnecting polyols with epihalohydrin in the presence of substantially an equimolar amount of base based on the epihalohydrin thereby forming an extended polyol with terminal hydroxyl groups and at least one hydroxyl group attached directly to the backbone chain internally. These resultant polyols can be used to make polyurethane foams having high resiliency.

Abstract: Disclosed herein is a polyurethane foam having good wet strength. The foam is prepared by reacting a urethane prepolymer with large amounts of water containing a poly(amino)urea and optionally other ingredients, e.g. surfactants. The poly(amino)urea is characterized as being the water soluble reaction product of a polyamine with a urethane prepolymer, said reaction product being further reacted with a crosslinking agent, e.g. epichlorohydrin.

Abstract: The invention disclosed is directed to new curable liquid polyene-polythiol compounds containing particular polar groups, at least one unsaturated carbon-to-carbon bond disposed at a terminal position on a main or pendant chain of the molecule and at least one terminally disposed thiol group, with the sum of the unsaturated bonds and thiol groups per polyene-polythiol molecule being at least 3. Upon curing in the presence of a free radical generator such as actinic radiation, the polar polyene-polythiol compounds form solid elastomeric and rigid products which are useful in a variety of applications including coatings, adhesives, sealants and molded articles.
