    Abstract: Fluorocarbon blowing agent compatible polyol blends are provided comprising reaction products of a combination of (a) a residue from the manufacture of dimethyl terephthalate, (b) a low molecular weight diol compound, (c) a nonionic surfactant compound, (d) optionally a hydrophobic compound, and (e) optionally a polybasic carboxylic acid compound. These polyol blends are produced by a simple heating process and are thereafter optionally blendable with various conventional polyols and other additives (including fluorocarbons and catalysts) to make resin prepolymer blends. Such resin blends can be catalytically reacted with organic isocyanates to produce cellular polyurethanes and polyurethane/polyisocyanurates.

    Abstract: A process is provided for making acyloxy benzene sulfonates by the steps of sulfonating with SO.sub.3, digesting the sulfonation adduct, and neutralizing. The sulfonation adduct can spontaneously rearrange. Unless the rearrangement is controlled as taught in the sulfonating and digesting steps, product yields of acyloxy benzene sulfonate drop to unusable levels and the color of the product is poor and the content of by-products is excessive in the product.

    Abstract: One-component (1K) adhesive compositions (“PEEP” compositions) and a process for making them are disclosed. A polyepoxide is reacted with a polyether polyol composition, a polyester polyol composition, or both in the presence of a heat-activated Lewis acid catalyst at a temperature within the range of 100° C. to 220° C. for a time effective to cure the adhesive. The compositions are storage-stable under ambient conditions. Compared with conventional epoxy compositions, the 1K PEEP compositions offer improved room temperature lap shear strength, better resilience, and higher elongation. The 1K PEEP systems deliver a desirable balance of physical and mechanical properties while avoiding polyisocyanates and polyamine crosslinkers.

    Abstract: Rigid polyurethane or polyisocyanurate foams, polyester polyols used to produce them, and methods for formulating the foams are disclosed. The foams comprise a reaction product of a polyisocyanate, a polyester polyol, water, a surfactant, a catalyst and optional ingredients. The polyester polyols comprise a phthalimide-containing polyacid, a phthalimide-containing polyol, or a combination thereof. Rigid foams produced from the polyester polyols exhibit higher thermal stability and/or greater intumescence when compared with foams made from other polyester polyols. The phthalimide-containing polyester polyols should allow formulators to improve the flammability performance of rigid foams with reduced levels of flame retardants and/or lower index and should facilitate the production of thinner insulation panels.

    Abstract: A method for inhibiting corrosion of pipelines and other metal surfaces, particularly those used in the oil-and-gas industry, is disclosed. The method comprises treating a brine-exposed metal surface with a film-forming composition. The composition comprises a quaternary surfactant, which is made by reacting a polyalkylene glycol (PAG), a haloalkanoic acid, and a tertiary fatty amine that optionally incorporates amide or ester functionality. The surfactant comprises a PAG monoester quat and a PAG diester diquat and may have other components. The quaternary surfactants provide good corrosion protection and can partition effectively from an oily phase into a brine phase in the absence of agitation. The surfactants are easy to synthesize economically and have structures that can be tailored to meet local HLB requirements.
