Abstract: Curable compositions, cured compositions, and articles that include the cured compositions are described. The curable composition contains a) an epoxy resin, b) a curing agent, c) a reactive liquid modifier, and d) a toughening agent. The reactive liquid modifier is an acetoacetate ester of a polyol that is a vegetable oil, that is prepared from a vegetable oil, or that is a mixture thereof. The cured compositions can be used as adhesives such as structural adhesives or as polymeric coatings.

Abstract: Biopolymeric hydrogel precursors are prepared by means of a ring-opening polymerization of epoxidized vegetable oils, followed by chemical hydrolysis. The recovered hydrogels having properties similar to Pluronic® type surfactants would have a plurality of end-use applications, including use as food additives and pharmaceutical ingredients. This invention provides the potential for an enhanced market for vegetable oils, and particularly for soybean oil.

Abstract: An epoxy adhesive composition of an epoxy resin, an epoxy terminated liquid rubber, filler, and an amine curing package for said epoxy resin is disclosed. Advantageously, a short chain diol will be incorporated into the adhesive in order to enhance reactivity and strength build. Advantageously, a mixture of amines will be used in the curative including multifunctional aliphatic amines that improve adhesion and strength build; tertiary amines which are used to enhance adhesion and strength build, polyamides which can be used to provide flexibility; and amine-terminated rubbers (ATBN) which can improve toughness and impact resistance to the cured system. The preferred short chain diol is glycerin. Surfaces of adherends are joined with the dried residue of the epoxy adhesive composition by applying the epoxy resin composition to one or both surfaces, joining the surfaces, and applying pressure, optionally with heating.

Abstract: An ambient curable aqueous dispersion of polymer particles containing pendant ethylenically unsaturated side chains; a method of applying to a substrate a coating composition containing the aqueous dispersion of polymer particles; and a method of making the aqueous dispersion of polymer particles are provided.

Abstract: A resin composition applicable to semiconductor or electric devices comprises (A) a polyarylenesulfide resin, (B) a bisphenol epoxy resin, (C) an oxazoline group-containing amorphous polymer, and (D) an impact resistance-improving resin which is either (d1) an acid or epoxy groups-containing vinyl polymer, or (d2) an acid or epoxy groups-containing gum polymer.

Abstract: Polyglycerol, lactose, and a combination of polyglycerol and lactose are effective at preserving cells, tissues, and organs from damage due to hypothermic, ischemic, or other metabolic impairment, and a mixture of polyglycerol plus lactose is particularly useful for the hypothermic storage of cells, tissues, and organs. The mixture of polyglycerol and lactose can be further improved by the addition of chondroitin sulfate, chlorpromazine, calcium, citrate, glutathione, adenine, glucose, magnesium, and a pH buffer.
