Abstract: The present invention includes interlayers and multiple layer glazing panels comprising those interlayers, wherein the interlayers comprise poly(vinyl butyral) and a glycerol based plasticizer. The addition of the glycerol based plasticizer surprisingly results in a plasticized poly(vinyl butyral) layer that is suitable for use in a wide range of multiple layer glazing applications.

Abstract: This invention provides a method of preparing a polymeric delivery system for active ingredients having enhanced site specific release performance characteristics. The delivery system is formed either by attaching the active ingredient to a linker through an acid-sensitive covalent bond, then forming a covalent bond between the linker and a portion of the subunits of a crosslinked polystyrene polymer, or by attaching a linker to a portion of the subunits of a crosslinked polystyrene polymer, then attaching the active ingredient to the polymer-linker combination through an acid-sensitive covalent bond. The invention also provides a delivery system comprising an active ingredient covalently bonded through an acid-sensitive covalent bond to a linker, which is in turn covalently bonded to a portion of subunits of a crosslinked polystyrene polymer.

Abstract: A process for the manufacture of phosphorous acid by selective hydrolysis of phosphite esters. A hydrolysis feed mixture comprising phosphite esters and phosphate esters is contacted with liquid water or steam to selectively hydrolyze the phosphite esters to phosphorous acid. The feed mixture may be prepared by oxidation of elemental phosphorous in the presence of an alcohol. In the oxidation and/or a subsequent esterification step, P(III) and P(V) oxyacids produced in the oxidation reaction are esterified, preferably quantitatively. The ester mixture may be washed to remove unesterified phosphoric and hypophosphorous acid, after which the selective hydrolysis is carried out.

Abstract: The present invention relates to the synthesis of a hydrazone .beta.-keto ester by the reaction of an alkyl diazoester with a hydrazone aldehyde in the presence of a Lewis acid In a preferred embodiment, the hydrazone .beta.-keto ester is then converted into a pyridazinone compound by the reaction with an alkyl acid chloride in the presence of a base, followed by acidification. A process for the production of a hydrazone aldehyde, which comprises contacting a hydrazine and glyoxal, is also described.
