Abstract: Epoxy resin compositions having improved storage stability before curing and improved thermal and mechanical performance after curing comprise a mixture of a polyepoxide and a curing agent that is reactive with the polyepoxide. The epoxy resin composition is characterized by a glass transition temperature of less than 20.degree. C., measured under standard conditions, after subjecting the epoxy resin composition to a specified thermal cycle. The preferred curing agents are aromatic diamines, for example, 3,7-diaminodibenzothiophene-5,5-dioxide; 3,7-diaminophenothiazine sulfone, 3,7-diamino-N-methylphenothiazine sulfone; 2,7-diamino-9-fluorenone and 2,4,6,8-tetramethyl-3,7-diaminothioxanthene sulfone.

Abstract: Disclosed are novel blends of peroxides that have melting points of about 5.degree. C. and lower. The blends consist essentially of (1) t-butyl cumyl peroxide, (2) bis(.alpha.-t-butylperoxyisopropyl)benzene, and (3) dicumyl peroxide.

Abstract: The present invention relates to a novel class of oligomeric builders for use in detergent compositions. More particularly, the present invention relates to a biodegradable, oligomeric polyacrylate having a molecular weight of greater than about 500 and less than about 10,000, preferably less than about 5000. In the most desirable embodiments at least one end of the oligomer chain is terminated with either a sulfur containing moiety or an hydroxy containing moiety. Preferred cations are alkali metals, ammonium and substituted ammonium.

Abstract: Substituted 2H-pyran-2,6(3H)-dione derivatives useful in the treatment of allergic conditions are prepared by reaction of 3,5-diacetyl-4,6-dihydroxy-2H-pyran-2-one with an appropriate aniline.

Abstract: Substituted aurones useful as inhibitors of certain antigen-antibody reactions, particularly in alleviating allergic manifestations such as asthma, are prepared by reaction of a 3-coumaranone with an appropriately substituted benzaldehyde followed by treatment with aqueous mineral acid and an alkanol.

Abstract: Substituted 2H-pyran-2,6(3H)-dione derivatives, pharmaceutical compositions comprising such derivatives and methods of inhibiting the antigen-antibody reaction by administering said compositions. The active ingredients are the products formed by the reaction of acetonedicarboxylic acid with acetic anhydride followed by reaction with an appropriate amine. Certain of the dione derivatives are novel compounds per se.
