Abstract
The present invention provides improved powder-free gloves having improved cleanliness as well as desired ergonomics over current natural rubber latex gloves. By controlling the formulation used to construct the gloves, a wide range of physical performance, aging resistance, as well as high cleanliness can be achieved. To this end, the present invention provides a powder-free glove constructed from a sequential copolymer. In an embodiment, the sequential copolymer is chosen from the group consisting of: poly(styrene-b-isoprene-b-styrene); poly(styrene-b-butadiene-b-styrene); poly (styrene-b-ethylene butylene-b-styrene); poly(styrene-b-ethylene propylene-b-styrene); radial and teleblock copolymers of the type (SI).sub.X, (SB).sub.X, and the like; and graft copolymers.
Claims6
A powder-free and protein-free multiple layered glove comprising an inner layer, an outer layer and a middle layer between the inner and outer layers wherein the inner and outer layers are each constructed from at least one sequential copolymer selected from the group consisting of:
- high styrene poly(styrene-b-isoprene-b-styrene), poly(styrene-b-butadiene-b-styrene), poly(styrene-b-ethylene butylene-b-styrene) and poly(styrene-b-ethylene-propylene-b-styrene) and the middle layer is constructed from poly(styrene-b-isoprene-b-styrene) wherein the styrene content of the high styrene sequential copolymers is greater than approximately 20wt. %.
