Abstract: A plasticized polyurethane gel system comprising the reaction product of an isocyanate compound and a polyol in the presence of a ricinoleate plasticizer compound having a total solubility parameter of between about 8.3 and 8.9 or between about 9.1 and 9.7. Said polyurethane systems are cured, cross-linked, nonspewing, grease compatible, and reenterable. This extended polyurethane is further characterized as having superior insulating properties so that it can be used of repairing, encapsulating or reclaiming electrical or telecommunication cables as well as for hard volume encapsulants or general elastomer use.

Abstract: Graft polyols comprising the liquid reaction product of a vegetable oil or unsaturated fatty carbon compound having at least eight carbon atoms, at least one hydroxyl group, and at least one double bond, a cyclopentadienyl compound and a terminally unsaturated monomer having at least one hydroxyl group. These liquid low viscosity polyols when cured with a polyisocyanate, melamine, or formaldehyde compound yield high solids or solventless polyurenthane compositions useful as coatings, adhesives, potting or molding compounds.

Abstract: A grease compatible cyclic olefin extended polyurethane comprising the reaction product of an isocyanate terminated polyisocyanate with a polyol in the presence of a cyclic olefin extender and, a plasticizer having a total solubility parameter of between about 8.3 and 8.9 or about 9.1 and 9.7. Certain extended polyurethanes are characterized as being reenterable, such that they can be used for repairing, encapsulation or reclaiming electrical or telephone cables. Alternate formulations can be used as hard volume encapsulants for general elastomer use.

Abstract: Low viscosity, high solids polyurethane coatings compositions are prepared from a diricinoleate derivate and an isocyanate or from a diricinoleate derivative, a high viscosity polyol, and an isocyanate. Also, a method for reducing the viscosity and increasing the solids content of a polyurethane coating by adding from about 1 to 99 percent by weight of a diricinoleate derivative to a hydroxyl bearing component before reacting with an isocyanate, and a method for preparing a polyurethane coating having a low viscosity suitable for spray coating applications by reacting a diricinoleate derivative with an isocyanate.

Abstract: A cyclic olefin extended polyurethane system comprising the reaction product of an isocyanate terminated polyisocyanate with a polyol in the presence of a cyclic olefin extender and, optionally, a liquid ester or other type of extender. Said polyurethane systems are cured, crosslinked, non-spewing, grease compatible, and reenterable. This extended polyurethane is further characterized as having superior insulating properties so that it can be used for repairing, encapsulation or reclaiming electrical or telephone cables as well as hard volume encapsulants for general elastomer use. The extended polyurethane is comprised of a defined polyurethane, novel extender combinations, and optionally, a coupling agent.

Abstract: A cured, cross-linked, mineral oil extended polyurethane which is non-spewing. The mineral oil extended polyurethane is further characterized by being grease compatible in that the tendency of the mineral oil to migrate is substantially reduced or eliminated. The mineral oil extended polyurethane is comprised of a defined polyurethane, mineral oil, and coupling agent. In other aspects, the present invention relates to a process for reclaiming or sealing an insulated electrical device and to an insulated electrical device which is formed by such process.

Abstract: A non-wicking polyurethane casting system has been developed which comprises the reaction product obtained by admixing a polyol containing N-N-N'-N'-tetrakis (2-hydroxypropyl) ethylene diamine, (hereafter referred to as QUADROL) with an isocyanate terminated polyurethane based prepolymer. This non-wicking casting system is useful as a potting compound in biomedical applications such as dialysis and hemoultrafiltration devices and the like.

Abstract: This invention provides a method of sealing and purging contaminants from the internal free spaces of an insulated electrical device by forcing into said free spaces a low viscosity material that acts to displace fluid contaminants from within said free spaces. The material later cures in situ to form a hydrophobic seal with good electrical properties. Also disclosed herein is a method for rehabilitating waterlogged plastic insulated multiconductor communications cables of the type employed in telephone system.

Abstract: Liquid 4,4'diphenylmethane diisocyanate (MDI) prepolymers have been produced which remain fluid and do not crystallize at temperatures below 40.degree. F. These prepolymers comprise the reaction product of a polyol, 4,4'diphenylmethane diisocyanate (MDI) and an aliphatic and/or cycloaliphatic diisocyanate. The polyol employed is selected from the group consisting of castor oil, polyoxypropylene glycol, polyhydric alcohol mono- and di-esters of hydroxyacids of at least 12 carbon atoms and mixtures thereof.The reaction product contains the polyol in amount from about 10% to about 40%, the 4,4'diphenylmethane diisocyanate in amount from about 50% to about 70% and the aliphatic or cycloaliphatic isocyanate in amount from about 10% to about 20%. The prepolymer should be prepared such that the NCO/OH ratio should fall within the range of about 3 to about 7.
