Patent number: 5807922Abstract: Novel organosilane derivatized long-chain compounds containing halosilane and hydroxysilane groups are disclosed and claimed. A process for the syntheses of these novel compositions is also disclosed, which involves simple one-pot hydrosilylation reaction of substituted halosilanes with substituted long-chain olefinic compounds, and subsequent hydrolysis to form surface active silanol derivatives. Preferred embodiments include organosilane derivatives of fatty acids derived from tung oil, high erucic acid rape seed oil, and linseed oil. These compositions feature high surface activity in forming stable organic/water emulsions of various difficultly emulsifiable materials as compared with conventional emulsifying agents. These compositions are useful as reactive-dispersants, defoamers, reactive-surfactants in emulsion polymerization, crosslinkers, film formers, gloss enhancers, anticorrosive additives, adhesion promoters and as general property enhancers in coatings, adhesives and inks.Type: GrantFiled: October 30, 1996Date of Patent: September 15, 1998Assignee: University of Southern MississippiInventors: Shelby Freland Thames, Kamlesh Gopichand Panjnani, Rajan Hariharan
