USING MIXTURE OF OXYETHYLATED CASTOR OIL AND ISOPROPYL ALCOHOL AS POLYMER SUSPENSION STABILISER Russian patent published in 2016 - IPC C08F2/18 C08F2/44 C08F120/12 C08F112/08

Abstract RU 2575850 C1

FIELD: chemistry.

SUBSTANCE: disclosed is use of a mixture of oxyethylated castor oil containing 9-12 ethylene oxide units and isopropyl alcohol, taken in volume ratio of 1:1, as a stabiliser in heterophase polymerisation of vinyl monomers in order to obtain stable monodispersed polymer suspensions with particle diameter in the range of 0.3-2.8 mcm.

EFFECT: wider range of biodegradable and environmentally safe surfactants which are used as stabilisers for a dispersion system when producing stable monodispersed polymer suspensions, wider range of diameters of the synthesized polymer microspheres.
