Abstract: This invention describes resins with phosphate cores and a simple, three-step process for their synthesis. Preferred resins are cyanate ester resins with bridging phosphate groups. These resins can be cured to produce thermoset polymers having Tgs of between 131 and >360° C. depending on the number of cyanate ester groups per phosphate and the substitution pattern of the aromatic rings. The high char yields of these resins, up to about 67%, coupled with the phosphate core means that these materials will have applications as fire-resistant polymers. Additionally, these materials can potentially be blended with conventional cyanate esters or other compatible thermosetting resins to improve the fire resistance of composite materials. Other applications may include use in fire-resistant circuit boards, or as surface coatings to reduce flammability of conventional composite materials or thermoplastics.

Abstract: The present invention provides a pigment/additive comprising discrete multivalent oxidation state (DiMVO) phenothiazine compounds having corrosion inhibiting properties. These novel DiMVO phenothiazines are useful in preparing waterborne primer coating formulations for application to metals and metal alloys and demonstrating corrosion inhibiting properties. Furthermore, such formulations are chromate-free and have reduced VOC content. Methods of preparing and using such compounds and waterborne formulations also are described.

Abstract: This invention is comprised of new nonlinear optic polymers and a new Lanir-Blodgett (LB) film deposition scheme for which these polymers were designed. The invention is unique because it produces an electro-optic film which has never undergone electric-field poling nor high temperature treatment. It eliminates the dilution effect of the long hydrophobic alkyl groups, and creates stronger ionic bonds between the polymer chains. Finally, the invention reduces the time to make a film of a given thickness by at least half by virtue of depositing two polymer layers per stroke. The new polymers are comprised of asymmetric chromophores linked head-to-head by alternating two different kinds of bridging groups. One of the bridging groups contains one or more ionic groups, and the other bridging group contains one or more non-ionic, hydrophilic groups.

Abstract: Until recently, conducting polymers have been used as protective coatings. lthough these types of polymers appear to be effective in most cases, problems have resulted when attempting to bind these polymers to an aluminum surface. The polymers of this invention adhere extremely well to aluminum and aluminum alloys and thus, provide a very effective form of corrosion protection.

Abstract: Novel conjugated amino substituted phenylene polymers are disclosed having on-linear optical properties, and which can be converted to electrically conductive polymers. Such polymers are produced by reacting a novel bis-cycloalkylene sulfonium salt of 2,5,N,N-tetramethylaniline hydrochloride, such as 2,5-(N,N-dimethyl)aniline hydrochloride dimethylene bis-(tetramethylene sulfonium chloride) with alkali metal hydroxide to form a cycloalkylene sulfonium salt precursor polymer, and then heating the precursor polymer under conditions to produce the amino substituted phenylene vinylene polymer, such as poly(2-(N,N-dimethylamino) phenylene vinylene). The polymers can also be made directly by treatment of the bis chlormethyl dimethyl aniline hydrochloride derivative with alkali metal alkoxide.

Abstract: A process that lends itself to automation for producing multi-layer second-order nonlinear optical polymer (NLOP) thin films by the forming of a polycation layer containing an NLO-active cationic polymer, having non-centrosymmetric chromophores, on a substrate followed by the forming of a polyanion layer, also having non-centrosymmetric chromophores, on the polycation layer. A predetermind number of the polycation and the polyanion layers may be alternated upon the surface as well as one or more buffer layers. An added benefit is the formation of an ultra-smooth surface of the same order of roughness as the substrate upon which the layers are formed.
