摘要：A solid composition exuding oil under pressure and constituted essentially of asolid, generally rigid, lattice of molecules of an acrylate polymer cross-linked withsufficient cross-linking agent up to a minor amount of yield a solid water-insolublepolymer, said lattice having non-volatile, non-drying oil occluded in situ uniformlytherethrough, the oil being present in the amount of about 35-80 percent by weight ofthe solid polymer, the oil being a solvent for the monomer and cross-linking agent and anon-solvent for the solid polymer but exerting at least a partial swelling or plasticizingaction on the polymer. The composition may be formed as structures varying fromshaped three-dimensional masses to discrete finely-divided particles. The compositionsare prepared by vorming an intimate admixture of the monomer and cross-linking agentin the oil and polymerizing the same in situ. Finely-divided particles are obtained by thefurther steps of dispersing the admixture of monomer oil solution in an aqueous mediumand effecting the polymerization while maintaining the dispersion.
