Abstract:
The present invention provides for a demulsifying composition comprising the reaction product of an oxirane or oxetane compound (I) comprising at least two oxirane or oxetane groups; a compound (II) comprising silicon and one or more amino groups; and optionally a polyamine (III); and a secondary amine (IV).
Abstract:
The present invention is related to the preparation and use of moderately cross-linked (chin-extended), reverse (or “inverted”) surfactants, wherein the reverse surfactants comprise a polyether backbone with oligomeric or polymeric silicon-containing substitutions along the backbone. The present invention further describes crosslinked versions of the inverted surfactants, reaction products of alkenyl (allyl, vinyl, methallyl) functional copolymers (polyethers), silicone hydrides and cross-linking agents, which may be optionally reacted with water to react the remaining alkoxy groups. The crosslinking agent contains either SiH or Si-alkoxy groups or both. The compounds of the present invention exhibit only moderate cross-linking in order to be soluble or dispersible in appropriate solvents.
