摘要： This invention is directed to a composition comprising expandable polymeric microparticles comprising hydrophobic polymers having a backbone with labile pendant groups, the microparticles having an unexpanded volume average particle size diameter of from about 0.05 to about 5,000 microns. Labile pendant groups on the backbone are subject to hydrolysis under a change in environmental conditions that results in expansion of the microparticle. The invention is further directed to the use of the composition for modifying the permeability of subterranean formations and increasing the mobilization and/or recovery rate of hydrocarbon fluids present in the formations.

摘要： This invention is directed to a composition comprising crosslinked expandable polymeric microparticles comprising structured polymers having labile crosslinks or having a labile core and non-labile crosslinks. The starting configuration of the structured polymers constrains the microparticle to an unexpanded volume average particle size diameter of from about 0.05 to about 5,000 microns. Labile crosslinks or the labile core of the structured polymers are subject to degradation which results expansion of the microparticle. The invention is further directed to the use of the composition for modifying the permeability of subterranean formations and increasing the mobilization and/or recovery rate of hydrocarbon fluids present in the formations.

摘要： A highly effective photoinitiator for cationic polymerization of monomer formulations is prepared by reacting diphenyl sulfide with chlorine gas in a Friedel-Crafts reaction in an organic solvent to form bis-[4-(diphenylsulfonio)phenyl] sulfide dichloride. This product is recovered and then reacted in an aqueous solution with a compound having the formula T.MF.sub.6 wherein M is one of phosphorus, antimony or arsenic and T is hydrogen or a metal whose halide salt is water soluble. The two compounds react in the aqueous medium to produce a precipitate which includes at least about 50 percent by weight bis-[4-(diphenylsulfonio) phenyl] sulfide bis-MF.sub.6, and this precipitate may be recovered and dried for utilization without further purification if so desired. Purification may be effected by dissolving the dried product in an organic solvent, cooling the solvent to precipitate the impurities, and thereafter recovering relatively pure bis-[4-(diphenylsulfonio) phenyl] sulfide bis-MF.sub.6 by chilling the solvent solution to form a precipitate, and then separating and drying the precipitate. The preferred compounds are those wherein the substituent M is phosphorus so that the product comprises bis-[4-(diphenylsulfonio)phenyl] sulfide bis-hexafluorophosphate. The cationic polymerization processes utilize the photoinitiator in an amount equal to about 0.5-6.0 percent by weight of the monomer therein.
