Disclosed is a method of making coagulant and viscoelastic compositions for use in removal of dispersed, solubilized, and emulsified oils and hydrocarbons and other noxious species from water and air. The composition comprises thermal reaction products of blends of fatty acids derived, isolated and purified from drying and semi-drying oils such as linseed, safflower, and tung oil with a polymer such as for example poly(isobutyl methacrylate) and can include a solvent. The product of the invention facilitates cohesion of oils and hydrocarbons independent of agitation and temperature and may be used in both salt and fresh water, air and other gaseous streams.La présente invention concerne des compositions viscoélastiques capables de prévenir la prolifération microbienne et capables de piéger les produits de décomposition de la membrane et de la paroi cellulaire des microbes, ces compositions comprenant des produits réactionnels d'huiles siccatives et d'huiles semi-siccatives et des polymères de méthacrylate. Les compositions sont capables d'absorber ou d'incorporer des lipopolysaccharides, des membranes protéiques et des endotoxines.
