Abstract
Abstract Impermeable relatively thin resin film having a granular textured surface which is adapted to be made into articles such as surgeons'' gloves is disclosed. The films are made from liquid dispersions of vinyl chloride polymers in a suitable plasticizer. The liquid dispersion or plastisol is applied to a suitable form to provide film of the resin dispersion thereon. The resin film is heat set and has applied thereto in a non-uniform distribution particles of a granular vinyl chloride polymer which becomes embedded therein, then the film is heat cured thereby forming a film having a granular textured surface.
