摘要:
A rubber article (such as a surgeon's glove) is provided with a skin contacting lubricating layer formed from a hydrogel polymer which is a copolymer of 2-hydroxyethylmethacrylate (HEMA) with methacrylic acid (MAA) and/or with 2-ethylhexyl acrylate (EHA) or other alkyl acrylate or alkyl methacrylate. Such hydrogel polymers have improved lubricity to dry skin.
摘要:
A flexible dipped rubber article having a lubricating layer formed from a hydrogel polymer bonded thereto so as to provide a skin-contacting surface of said article, characterised in that the lubricating layer is formed by applying a solution of a hydrophilic hydrogel-forming polymer to the dipped rubber article prior to complete vulcanisation thereof, and curing the polymer and vulcanising the rubber.
摘要:
A skin-contacting lubricating layer formed from a hydrogel polymer bonded to a rubber article (such as a surgeon's glove) is treated by means of surfactant material (such as a bactericidal cationic surfactant which preferably has a 6-18C alkyl or alkenyl group, such as an N-hexadecyl group) or a long chain fatty amine so as to substantially improve the lubricity of the layer with respect to damp skin. The hydrogen polymer is preferably a copolymer of 2-hydroxyethylmethacrylate (HEMA) with methacrylic acid (MAA) or with 2-ethylhexyl acrylate (EHA) or with both MAA and EHA. Such a hydrogel polymer has improved lubricity to dry skin and, if used for this purpose, need not be treated with a surfactant or fatty amine to improve the lubricity with respect to damp skin.

摘要:
A hydrogel polymer-based lubricating layer is provided on a flexible rubber article (such as a surgeon's glove) or other polymer article by applying a solution having dissolved therein a hydrophilic hydrogel-forming polymer (such as a copolymer of 2-hydroxyethyl methacrylate) and a salt of a trivalent cation (such as aluminium). The polymer is cured after application to the substrate preferably with simultaneous vulcanisation of the rubber.
