F-5113-L POLYMER-COATED SUPPORT AND ITS USE AS SAND PACK IN ENHANCED OIL RECOVERY ABSTRACT OF THE DISCLOSURE A non-friable support, e.g., sand, coated with a polymer is prepared by contacting the support containing a polymerization catalyst with a monomer which is at least one multi-functional olefin, e.g., a diene, under monomer polymerization conditions. The product of the polymerization process is a highly cross-linked coating which engulfs the support, thereby rendering it hydrolytically and thermally stable. The support can be used as a sand pack in enhanced oil recovery operations, wherein it is resistant to deterioration due to high temperature, pressure and alkaline conditions existing in the subterranean formations.
