The invention relates to a method for the manufacture of a prophylactic article, especially of a glove, from a (carboxylated) diene rubber, according to which a layer of a (carboxylated) diene latex is applied on a former and the (carboxylated) diene latex is cross-linked with a cross-linking agent, which is immobilized on inorganic and/or organic particles with formation of modified particles, and the modified particles are added to the (carboxylated) diene latex.

Method for producing a prophylactic article

According to a method for the manufacture of a prophylactic article, especially of a glove, from a (carboxylated) diene rubber, at least one layer of a (carboxylated) diene latex is applied on a former and the (carboxylated) diene latex is cross-linked with a cross-linking agent, wherein a mercapto-functional siloxane polymer is used as cross-linking agent.

The invention relates to a method for modifying the surface of an elastomer product with unsaturated carbon-carbon bonds, in particular a glove, whereby the unsaturated carbon-carbon bonds in the region of the surface are at least partially saturated by a photochemical reaction with at least one thiol or by applying or dipping to apply a layer of latex to at least certain regions of the surface of the elastomer product, the unsaturated carbon-carbon bonds of which in the region of its surface are at least partially saturated by a photochemical reaction with at least one thiol.

Method for modifying the surface of an elastomer product

The invention relates to a method of bonding particles to the surface of an elastomer, in particular a glove, the surface of the elastomer being at least partially epoxidized, and the particles are covalently bonded to the epoxide groups after epoxidation of the elastomer surface.

Elastomer product with covalently bonded particles

The invention relates to method for producing a crosslinked elastomer by radiating a polymer dispersion of at least one crosslinkable polymer with electromagnetic radiation in the ultraviolet (UV light) and/or visible spectral range, wherein the crosslinking is performed in at least two stages as pre-crosslinking and post-crosslinking and at least one photoinitiator is added to the polymer dispersion to trigger the crosslinking reaction prior to the pre-crosslinking. At least one photoinitiator is added once again to the pre-crosslinked polymer dispersion prior to and/or during the post-crosslinking, and the post-crosslinking is also performed with electromagnetic radiation in the ultraviolet (UV light) and/or visible spectral range.
