Abstract:
Disclosed is a method of preparing terminally functionalized telechelic polymers using a cationic living polymer product or a terminal tert-chloride chain end of a carbocationic quasiliving polymer product, which comprises quenching the polymer product with an N-substituted pyrrole to thereby functionalize the N-substituted pyrrole at the terminal reactive polymer chain end(s). Also disclosed are the terminal functionalized polyisobuyl N-substituted pyrrole compounds where the polyisobutyl group is subsitituted at the 2 and 3 position of the N-substituted pyrrole.
Abstract:
The colloidal dispersion of the invention is characterized in that it comprises an organic phase; particles of an iron compound in its amorphous form; and at least one amphiphilic agent. It is prepared by a process in which either an iron salt in the presence of an iron complexing agent or an iron complex is reacted with a base, maintaining the pH of the reaction medium at a value of at most 8 to obtain a precipitate, the iron complexing agent being selected from hydrosoluble carboxylic acids with a complexing constant K such that the pK is at least 3 and the iron complex being selected from the products of reacting iron salts with said acids; then the precipitate obtained or a suspension containing said precipitate is brought into contact with an organic phase in the presence of an amphiphilic agent to obtain the dispersion in an organic phase. The dispersion of the invention can be used as a combustion additive in liquid fuel or motor fuel.

Abstract:
The present invention is directed to a method of providing enhanced molecular stability to hydrocarbons, such as the various oils, lubricants, fuel and rubbers typically used in internal combustion engines. The invention generally comprises inhibiting the liquid phase oxidation of hydrocarbons by atmospheric oxygen at elevated temperatures through the micro-addition of non-toxic of alkyl organic additives. The alkyl organic additives are anionic surface active agents (ASAAs) of the general formula RnullOSO3M or RnullOP3Z2, where nullMnull is Na or K, where nullZnull is Na, K or an alkyl group containing between ten and fourteen carbons and where nullRnull is an alkyl group consisting of between six and sixteen carbons. The additives are generally used in quantities from 0.01 to 10 mass percent, at temperatures between 70null-170null C. and in the presence of an aromatic solvent.

Abstract:
The additive described essentially comprises a selected alkoxylated fatty amine or fatty amine derivative and a special metal salt compound, preferably a metal soap. This additive for heavy oils effects a good emulsification or dispersion of asphaltenes and other higher-molecular weight compounds and, in addition, inter alia, increased storage stability, improved pumpability due to decreased viscosity of the oil and longer service lives of the filter systems. In addition, it also effects enhanced combustion of the heavy oils. The effective amount of additive in these oils is 2 to 2000 ppm. The oils described are suitable, in particular, as furnace fuel for industrial plants and power stations and as engine fuel for marine engines.
Abstract:
Inhibitors of wax deposition for crude oils are polymers of a monomer with structural units derived from at least one ester (i) of an aliphatic carboxylic acid with an aliphatic alcohol, wherein one of the acid and alcohol is ethylenically unsaturated and the other of the acid and alcohol has a long chain group of 14-40 carbons, and a monomer with structural units derived from a corresponding ester (3) with structural units derived from an aliphatic carboxylic acid and an aliphatic alcohol, wherein one of the acid and alcohol is ethylenically unsaturated and the other has an aliphatic group of 1-13 carbons, such that at least 30% preferably 50-90% of the said aliphatic groups have 15-35 carbons. They are preferably made by transesterification. Blends of such polymers and/or the corresponding homopolymers or copolymers of ester 1 and/or polyalkylene imines with long side chains, and optionally with monomeric polar additives may be used as inhibitors.
Abstract:
The present invention is directed to an oil-soluble lubricating oil additive comprising at least one terminally unsaturated ethylene/alpha-olefin/diene interpolymer of 300 to 20,000 number average molecular weight substituted with mono- or dicarboxylic acid producing moieties (preferably dicarboxylic acid or anhydride moieties), wherein the terminal unsaturation comprises terminal ethenylidene unsaturation. The mono- and dicarboxylic acid or anhydride substituted interpolymers of this invention are useful per se as additives to lubricating oils, and can also be reacted with a nucleophilic reagent, such s amines, alcohols, amino alcohols and reactive metal compounds, to form products which are also useful lubricating oil additives, e.g., as dispersants.
