Abstract: A synthetic polyisoprene latex emulsion has pre-vulcanization composition and post vulcanization composition. The pre-vulcanization composition comprises soluble sulfur with high S8 ring structure that is catalytically broken by a zinc dithiocarbamate. Surfactants present in the pre-vulcanization composition wets synthetic polyisoprene particles and permeates small sized sulfur and accelerator molecules into the interior of these particles thereby pre-vulcanizing the particles. The degree of pre-vulcanization is verified by isopropanol index test. The latex emulsion has post-vulcanization composition with accelerators that crosslink inter-particle region during post vulcanization cure cycle. The dipped synthetic polyisoprene article is substantially uniformly cured both in the inter-particle and intra-particle regions and reliably exhibits high cross link density, uniform distribution of double bonds in TEM and zinc segregation at the boundaries or original particles by electron microprobe analysis.

Abstract: Lightweight robust flexible gloves having an 18 gauge knitted liner and a polymeric coating disposed thereon and optionally including knitted reinforcement sections at areas of high stretch and/or movement are provided. Reinforcement sections can be formed by plaiting, using yarns of the same or lighter denier, and/or forming Jacquard or transfer stitches.

Abstract: A cut resistant chemical handling glove that is flexible and lightweight comprises a cured, liquid-impervious polymeric latex shell. A tacky acrylic adhesive with low shear strength can be used. A cut resistant liner is slipped on the tacky adhesive coating and is infiltrated with a polymeric latex coating and cured to integrally attach the cut resistant liner with the cured polymeric coating. When the latex glove is worn on a hand and a cutting edge, such as a knife edge, contacts the glove, a crease is formed due to slip at the tacky adhesive-cut resistant liner interface creating a geometry that reduces cut stress intensity at the knife-edge thereby increasing the cut resistance of the glove. Processes for making and using these gloves are also described.

Abstract: Latex articles with geometrically defined surface structure providing enhanced grip characteristics in dry, wet or oily environment; and a method of making same comprising applying a polymeric coagulant coating to a smooth former surface, wherein the coating becomes tacky during drying, applying discrete coagulant particles of selected size, shape and distribution to the tacky coating to attach and protrude from the former surface with the polymeric coagulant coating, dipping the former into an aqueous latex emulsion, wherein the polymeric coagulant coating and the discrete coagulating particles destabilize the latex, thereby developing a latex layer, vulcanizing and stripping the latex article inside out, and dissolving the discrete coagulant particles in water or suitable solvents to reveal the geometrically designed texture with pre-selected size, shape and distribution of impressions providing improved dry, wet and oily surface grip by removal of a fluid boundary layer.

Abstract: A lightweight thin flexible latex glove article having a polymeric latex coating that penetrates the front portion of a knitted liner half way or more through the liner thickness and for at least a portion of the knitted liner, not penetrating the entire thickness. For example, the liner can be knitted using an 18-gauge needle with 70 to 221 denier nylon 66 multi-filament yarn. The polymer latex coating can be 0.75 to 1.25 times the thickness of the knitted liner. Over 30% reduction of glove thickness is achieved resulting in three times greater flexibility. The polymer latex coating may be foamed with 5 to 50 vol % air content. Open celled foamed latex coating may be coated with a dispersion of fluorochemical dispersion to prevent liquid permeation into the glove. The process can include steps to gel the latex emulsion at interstices of the yarn to prevent further penetration of the emulsion into the liner.

Abstract: An odor control additive present in a litter formulation provides release of fragrance or odor masking scent only when litter is used by a cat or other animal within a litter box. The odor control additive comprises a plurality of fragrance scent microcapsules that contain fragrance scent oil. This central, fragrance scent oil is encapsulated in a microcapsule cell wall, which prevents evaporation of the fragrance scent oil and prevents overpowering of litter smell in a closed room resembling an unscented litter composition. When cat or animal enters the litter box, a load is applied to the fragrance scent microcapsules, which readily breaks releasing the fragrance contained therein. The fragrance scent microcapsule cell walls also degrade by swelling and degradation when wet by animal urine thereby releasing fragrance. Fragrance evaporating from the ruptured microcapsules provides odor control and a pleasant scent.
