Process for producing improved silica-reinforced masterbatch of polymers prepared in latex form
A process for the incorporation of silica into a polymer in latex in which a silica is treated with an organo silicon compound coupling agent in aqueous suspension to form a compatibilized silica and then contacting a polymer latex with the compatibilized silica whereby the silica becomes substantia...

Summary: | A process for the incorporation of silica into a polymer in latex in which a silica is treated with an organo silicon compound coupling agent in aqueous suspension to form a compatibilized silica and then contacting a polymer latex with the compatibilized silica whereby the silica becomes substantially uniformly distributed throughout the latex and can be recovered when the latex is coagulated to yield little residual silica in the liquid residue from the latex. Also described is a process for preparing the compatibilized silica. |
