The invention is directed to oligo/polysuccinimides prepared from alkyl or alkenyl succinic anhydride, containing two or more imide groups, a method for producing such oligo-polysuccinimides, and the use thereof as dispersing agents in lubricant products, plasticizers in plastics, surface sizes for paper industry, reactive additives, for coating and composite applications, as well as encapsulating agents in pharmaceutical and speciality chemical products. In the method, a linear or branched C&#x2013;Calkyl or alkenyl succinic anhydride is reacted with an oligoamine having two or more primary amino groups to obtain the corresponding oligo/polysuccinimide.

Oligo/polysuccinimides, process for producing thereof and their use

The present invention concerns a paint composition which comprises a binder, a coalescent agent and optionally admixtures and auxiliary agents known per se. The film forming agent comprises a glycidyl ether or glycidyl ester or a mixture thereof, the hydrocarbyl residue of the alcohol or carboxylic acid, respectively, of the ether or ester comprising a linear or branched, saturated or unsaturated hydrocarbon having 3 to 20 carbon atoms. The invention further concerns a method of accelerating the hardening of paint compositions and a novel method of preparing glycidyl esters. The film forming agents used in the invention lower the film forming temperature better than conventional reactive film forming agents. Due to low volatility the compounds are suitable for no-VOC applications.

Paint compositions

The invention concerns a process for manufacturing polyol complex esters. According to the method, a polyol, such as BEPD or NPG, is reacted with mono- and polyvalent acids in the presence of a catalyst to produce a reaction blend containing complex esters. According to the invention the acid components of the reaction blend are neutralized with a tertiary amine, and the complex esters are recovered from the thus treated reaction blend. The basic amines that are used form salt-like compounds with the carboxylic acids. The compounds enter the aqueous phase, from which they are easily separated, whereby the complex esters are recovered with high yield.

Process for selective hydrogenation of unsaturated polymers

The present invention relates to N acyl and O acyl derivatives of N,N-bis(2,2-dimethyl-3-hydroxypropyl)amine which are produced as follows: ammonium halide, sulphate or aldehyde, and isobutyl aldehyde are subjected to condensation reaction and the obtained product is reduced to the corresponding amino alcohol. The hydrogen atoms linked to the nitrogen atom and the oxygen atom are thereafter substituted by acyl groups. The N-acylation and esterification of hydroxyl groups can be performed simultaneously using a carboxyl acid, carboxyl acid halide, or carboxyl acid anhydride. The N,N-bis(2,2-dimethyl-3-hydroxypropyl)amine derivatives can be used as polymer stabilizers, PCV plasticizers, emulsifiers, corrosion resistance agents, and metal complexing agents.

Catalyst system for selective alkylation of toluene

The invention concerns a procedure for manufacturing short-chain linear .alpha.-olefines, in particular 1-butylene, selectively from ethylene. A nickel chelate in which the ligand is diphenyl (2-carboxymethyl) phosphine, diphenyl (2-carboxyethyl) phosphine, or an alkali metal salt of these, or an alkali metal salt of diphenyl (2-hydroxyethyl) phosphine, with or without a promoter, is used for a catalyst.
