Abstract: The present invention relates to itaconamide compounds of the formula ##STR1## wherein R is hydrogen, alkyl, aryl, alkaryl, or aralkyl and to a method of preparing the subject compounds which comprises preparing a mixed anhydride of 2-methylenesuccinamic acid and reacting the mixed anhydride with a compound of the formula RNH.sub.2, wherein R is as previously defined, to provide the corresponding itaconamide compound.

Abstract: Alkyl ammonium nitrate fused salts of the formula ##STR1## wherein R.sup.1 is a substituted or unsubstituted alkyl group and R.sup.2 and R.sup.3 are each independently hydrogen or a substituted or unsubstituted alkyl group, which fused salts have melting points of up to about 125.degree. C., are disclosed for use as solvents or swelling agents for polymers and as polymerization media for the conduct of polymerization reactions.

Abstract: A process for preparing 2-methylene-1,3-propanediamide is disclosed which comprises providing a solution of a novel compound of the formula ##STR1## wherein R.sub.1, R.sub.2, and R.sub.3 can each independently be lower alkyl of from 1 to 10 carbon atoms, aryl, alkaryl, aralkyl, or halogen and X is an electron-accepting leaving group, in an inert, aprotic organic solvent, and subjecting the compound in solution to .beta.-elimination reaction conditions effective to eliminate the silyl group ##STR2## and the electron-accepting leaving group--Xfrom the compound to form a double bond between those carbon atoms to which the silyl group and the electron-accepting leaving group were bonded, thereby forming 2-methylene-1,3-propanediamide. 2-Methylene-1,3-propanediamide is useful in preparing polymers which can be used in preparing coating compositions, films, and filaments.

Abstract: A process for preparing polyfunctional methylene-bridged compounds is disclosed. A difunctional methylene-bridged compound having acidic protons and having the formula X--CH.sub.2 --X is reacted with an alkali metal in the presence of a disubstituted formamide to provide a methylene-bridged polyfunctional compound having the formula ##STR1## wherein X is an electron-withdrawing group such as --CONH.sub.2, --COOR or --SO.sub.2 R where R is alkyl. The polyfunctional compounds prepared by the process of the present invention are useful in the production of metal complexing or sequestering agents, acidulents, cross-linking agents for polymeric reactions and in applications where a polyfunctional compound is desirably employed.

Abstract: Processes are disclosed for providing in situ generated cyanic acid and simultaneously preparing certain carboxamides which have a tertiary aliphatic substituted ammonium or pyridinium group substituted on the alpha carbon atom.

Abstract: Benzoyl peroxide compounds containing reactive substituents are used to initiate the formation of telechelic polymers.

Abstract: This invention relates to methods of generating colored images by treatment of maleimide copolymers with ammonia or organic amines.

Abstract: Processes are disclosed for providing in situ generated cyanic acid and simultaneously preparing certain carboxamides which have a tertiary aliphatic substituted ammonium or pyridinium group substituted on the alpha carbon atom.

Abstract: A copolymer soluble in aqueous and/or partially aqueous solution and having a chain comprising the entities A and B defined below: ##STR1## WHEREIN: M is hydrogen or methyl;R is an alkylene group comprising less than six carbon atoms or a substituted alkylene group;Each D is hydrogen, methyl or ethyl; andn is the total number of A and B residues in the polymer chain.The copolymers are useful as hardeners for protein-containing emulsions, especially, for example, gelatin emulsions employed in the photographic art. The copolymers of the present invention can also be advantageously employed to selectively adjust the viscosity of protein-containing emulsions to predetermined levels.
