New adducts are produced from the reaction of vinyl dioxo compounds with anhydrides, epoxyesters, lactones, and lactams, and such adducts are useful for preparing curable coating compositions.

Compounds having the structure ##STR1## and pharmaceutically acceptable salts thereof, wherein Z is oxygen, sulfur or methylene; R.sub.1 is hydrogen, halogen, alkyl, aryl or arylalkyl; R.sub.2 is hydrogen, alkyl, aryl, or arylalkyl; R.sub.3 is hydrogen, alkyl, aryl or arylalkyl; and R.sub.4 is hydrogen, halogen, alkyl, phenyl, dialkylamidosulfonyl or trifluoromethyl, have useful central nervous system activity.

A curable composition comprising a) an epoxy resin having on average more than one epoxide group per molecule and b1) an alkyldipropylenetrimine of general formula (I) and/or b2) an adduct of an alkyldipropylenetrimine of general formula (I) with b3) an epoxide compound having on average at least one epoxide group per molecule in which R is hydrocarbon radical 8 to 22 carbon atoms, and the use of this composition for mineral and metallic substrates. ##STR1##

Hydrogen fluoride adducts and ammonium fluorides are used for fluorinating acid chlorides and halocarbon compounds such as chloroalkanes or chloronated ethers. The used adducts can be regenerated and then reused in the fluorination reactions.

This invention relates to rosin carboxypyrrolidinone adducts. In particular, this invention relates to water-soluble resins derived from the reaction product of a modified rosin with a hydroxyl-containing carboxypyrrolidinone derivative. These resins can be used to make acrylic latex compositions which can, in turn, be utilized to produce water-based flexographic and gravure ink formulations.

This invention relates to bisulfite adducts of L-Arginine aldehyde derivatives, pharmaceutical formulations containing those adducts and methods of their use as thrombin inhibitors, coagulation inhibitors and thromboembolic disorder agents.

Organophilic polyphenolic materials which are effective fluid loss control additives for oil base well-working fluids are prepared from a polyphenolic material and one or more phosphatides. Preferred phosphatides are phosphoglycerides obtained from vegetable oils, most preferably commercial lecithin. Preferred polyphenolic materials comprise one or more of: humic acid; lignosulfonic acid; lignins; phenolic condensates; tannins, the oxidized, sulfonated, or sulfomethylated derivatives of these po...

The present invention provides a method to prepare an adduct of a nitrile rubber and an amino alcohol. The present adducts have 2-oxazoline functionality which is detectable in the infrared spectrum.
