Abstract

An elastomeric article such as a glove includes a substrate body made of an styrene-ethylene-butylene-styrene block copolymer, and a donning layer overlying at least one side of the substrate body. The donning layer is formed of 1,2 polybutadiene, preferably syndiotactic 1,2 polybutadiene, or a chlorinated mid block unsaturated block copolymer. Optionally, a surfactant layer is present over the donning layer to further improve the donning characteristics. The surfactant layer is preferably an alkyl dimethylbenzyl quaternary, an alkyl trimethyl quaternary, a dialkyl dimethyl quaternary, sodium lauryl sulfate, or pyridinium chloride.

Claims

1. An elastomeric article, comprising:

a substrate body made of an elastomeric material; and

a donning layer overlying at least one side of the substrate body, the donning layer comprising 1,2 polybutadiene.

2. The elastomeric article of claim 1, wherein the substrate body has the form of a glove having an inside surface, and the donning layer overlies the inside surface of the glove.

3. The elastomeric article of claim 1, wherein the elastomeric material of the substrate body comprises a mid block saturated styrene block copolymer.

4. The elastomeric article of claim 1, wherein the elastomeric material of the substrate body comprises a styrene-ethylene-butylene-styrene block copolymer.

6. The elastomeric article of claim 1, further including a surfactant layer overlying the donning layer.

7. The elastomeric article of claim 1, further including

a surfactant layer overlying the donning layer, the surfactant layer comprising a surfactant selected from the group consisting of a cationic surfactant, and a cationic surfactant and a silicone antifoam.

8. The elastomeric article of claim 1, further including

a surfactant layer overlying the donning layer, the surfactant layer comprising a surfactant selected from the group consisting of an alkyl dimethylbenzyl quaternary, an alkyl trimethyl quaternary, a dialkyl dimethyl quaternary, a pyridinium chloride, sodium lauryl sulfate, and polydimethyl siloxane emulsion.

9. The elastomeric article of claim 1, wherein the donning layer polymer comprises syndiotactic 1,2 polybutadiene.

10. An elastomeric article, comprising:

a substrate body made of an elastomeric material;

a donning layer overlying at least one side of the substrate body, the donning layer comprising a chlorinated mid block unsaturated block copolymer; and

a surfactant layer overlying the donning layer, the surfactant layer comprising a surfactant selected from the group consisting of a cationic surfactant, and a cationic surfactant and a silicone antifoam.

11. The elastomeric article of claim 10, wherein the cationic surfactant is selected from the group consisting of an alkyl dimethylbenzyl quaternary, an alkyl trimethyl quaternary, a dialkyl dimethyl quaternary, a pyridinium chloride, and sodium lauryl sulfate.
