    摘要： Adducts, improved polymer-polyols and improved polyurethane foams are provided. The adducts are produced by reacting suitable polyol and epoxy co-reactant to essentially eliminate all epoxy groups. The polymer-polyol is produced by polymerizing suitable ethylenically unsaturated monomer in the adduct or in the adduct forming mixture; in the later case the adduct forming reaction and the polymerization reaction occur simultaneously to produce the polymer-polyol. Polyurethane foams are produced by the usual method but employing the novel adduct or polymer-polyol of the present invention.

    摘要： A stable, highly branched polyurethane prepolymer which is in liquid form is prepared by the conversion of polyether/polyols having at least four hydroxyl groups to a polyurethane by reaction with an excess of a urethane-forming reactant such as a polyisocyanate. The said excess functions as a solvent for the prepolymer and in this dissolved, stable form the prepolymer can be converted to rigid foams which have K factors of about 0.14 and below 0.22 and which have closed cell contents of about 90 percent, the cells being fine, uniform cells. In the conversion to the foams the prepolymer is reacted with additional polyether/polyol, this being a polymeric hydroxy compound prepared by reacting a compound containing four or more hydroxyl groups with an alkylene oxide, such as propylene oxide. The foaming is effected in the presence of a blowing agent which consists of a volatile, halogenated lower alkane containing chlorine and fluorine atoms. The iscoyanato content of the prepolymer is about 22 percent to about 30 percent and the final polyurethane has its molecular weight made up to an extent of about 65 percent to about 80 percent by the said polymeric hydroxy compound. Since the foaming is effected without the use of water, the nitrogen atoms in the reaction go substantially to form urethane linkages. The polyether/polyol is represented by such materials as the propylene oxide adducts of sorbitol or sucrose while the urethane forming reactant is represented by such a material as toluene diisocyanate and the blowing agent by such a material as monofluorotrichloromethane. The stability of the prepolymers and their liquid form afford ready shipment of the various components for the foams over long distances and storage for substantial time lengths.

    摘要： Novel modified polyether polyols made by first optionally alkoxylating, subsequent reaction with epoxy resins and final alkoxylation of mixtures of initiators is described. The initiator mixture is made up of about 60 to 90 wt. % of a partially alkoxylated trifunctional initiator and 10 to 40 wt. % of a secondary partially alkoxylated initiator having an active hydrogen functionality of from 4 to 8. Preferably, the alkylene oxide component is a blend of ethylene oxide and propylene oxide, and the resulting modified polyol molecules have 0.25 to 2.5 wt. % internally located epoxy resin. Flexible polyurethane foams made from these polyether polyols have improved load bearing properties as compared with those made from prior art polyols.

    摘要： Resin composition suitable for high-solids, solvent-based coating composition comprises chain-extendable, crosslinkable polyol of molecular weight of about 100 to 1000, having at least three hydroxyl groups, chain-extendable diblocked diisocyanate of molecular weight about 200 to about 2000, crosslinking agent reactive with the hydroxyfunctionality of the polyol and substantially unreactive with de-blocked isocyanate functionality of the diblocked diisocyanate, and, preferably, catalyst(s). The composition cures at elevated temperature to provide a coating on a substrate, such as steel, which coating is highly resistant to corrosion, humidity and solvents and provides corrosion protection for the substrate. The diblocked diisocyanate is the reaction product of an organic diisocyanate with monofunctional blocking agent. The polyol is preferably the reaction product of a diol of molecular weight about 60 to about 500 with a diepoxide of molecular weight about 100 to about 1000 such as bisphenol A epichlorohydrin epoxy resin, hydantoin epoxy resin and the like.
