Abstract: The disclosure sets forth aqueous cationic surfactant formulations and a process for their preparation. The formulations contains in solution a) from 10 to 50% by weight of a quaternary ammonium compound of the formula I:where: the substituents have the meanings set forth in the description, and b) from 0.01 to 15% by weight of an amine of the formula III:and c) from 0.1 to 5.0% by weight of a buffer which maintains a pH in a range from 4 to 9. The surfactant formulation is prepared by reacting an amine of the formula IIIin aqueous solution with a dialkyl sulfate of the formula IVwhere R1 to R5 are in a molar ratio range from 85 to 99.99 mol %, based on the amine and at from 20 to 100 degrees C. and then adding to the reaction solution from 0.1 to 5.0% by weight of a buffer which maintains a pH in a range from 4 to 9.

Abstract: An ethylene terpolymer wax comprises units derived from ethylene (40-95 wt.%), units derived from at least one anhydride of 4-10C-dicarboxylic acid having ethylenic carbon-carbon double bond (0.1-40 wt.%), and units derived from ester having a molecular weight of up to 20000 g/moles (0.1-40 wt.%). An ethylene terpolymer wax comprises 40-95 wt.% units derived from ethylene, 0.1-40 wt.% units derived from at least one anhydride of 4-10C-dicarboxylic acid having ethylenic carbon-carbon double bond, and 0.1-40 wt.% units derived from ester of formula I having a molecular weight of up to 20000 g/moles. R1 = H, 1-10C alkyl, 3-12C cycloalkyl, or 6-14C aryl (preferably H or Me); R2 = 1-10C alkyl, 3-12C cycloalkyl, or 6-14C aryl (preferably Me) An Independent claim is also included for preparation of ethylene terpolymer wax by polymerizing ethylene, ester (I), and anhydride of 4-10C dicarboxylic acid at 500-4000 bars and 170-300degreesC.
