Process for producing polymeric glove, which has different properties at outer and inner layers, and polymeric glove produced by same process

Abstract

A polymeric glove is made by a process wherein a glove form is dipped into a first bath containing a solvent and a first polymer, which when solidified has a first property, and the first polymer is solidified, wherein the glove form, on which the first polymer has solidified, is dipped into a second bath containing a solvent and a second polymer, which when solidified has a second property differing from the first property, and the second polymer is solidified, and wherein what results is stripped from the glove form, so as to invert what results. The polymeric glove has an outer layer having the first property, an inner layer having the second property, and an intermediate, transitional layer. The first property may be a comparatively higher coefficient of friction of an outer surface, which is defined by the outer layer, or may be a comparatively lower stiffness or a comparatively greater elasticity. The second property may be a comparatively lower coefficient of friction of an inner surface which is defined by the inner layer, or may be a comparatively higher stiffness or a comparatively lesser elasticity.
