Abstract: The instant invention is directed to a process for removing odor from alkylthioethylamine reaction product mixtures having said odor. The process comprises first contacting an alkylthioethanamine reaction product mixture with a neutralizing amount of aqueous alkali metal hydroxide to form an organic phase and an aqueous phase. Next, the organic phase is separated from the aqueous phase. After separation, a sufficient amount of an aqueous hydrohalic acid is added to the organic phase to form an alkylthioethanamine hydrohalide which has reduced odor.

Abstract: The present invention provides amphipathic graft copolymers which comprises a hydrophobic polymer portion to which is grafted at least one amphipathic polymer portion containing pH independent ionic groups. The amphipathic graft copolymers can be prepared employing a procedure which comprises polymerizing at least two hydrophobic monomers, wherein at least one of the monomers is a graftable monomer, and at least one hydrophilic monomer, including at least one anionic and/or cationic pH independent ionic monomer, or a post reactive non-ionic monomer that can be converted to a pH independent ionic derivative, in a reaction medium and recovering the thus prepared amphipathic graft copolymer. Stable, substantially non-aqueous solution compositions of said amphipathic graft copolymer containing less than 15 percent by weight water are also provided.

Abstract: Stable emulsions of water-insoluble organic pesticides are formed by mixing the pesticide with an aqueous dispersion of a graft copolymer comprising a reactive polymeric surfactant base polymer and a nonionic hydrophobic grafted composition. The graft copolymer spontaneously absorbs organic pesticides with low water solubility upon simple mixing. The resulting product is much more stable to coalescence than emulsions made with conventional or polymeric surfactants.Emulsifiable organic based concentrates, having a continuous oil phase, which are formed from admixtures of pesticidally active water-insoluble organic pesticides with graft copolymers can be diluted with or in water, thus, inverting the continuous oil phase to stable water based oil-in-water emulsions of the active pesticide.
