    摘要: The invention disclosed herein relates to an improved process for making elastomeric polyisoprene articles. In particular, the process of the invention is a system which produces synthetic polyisoprene articles exhibiting tensile strength properties similar to that of solvent-based processes using natural rubber latex. The process comprises an accelerator composition at the pre-cure stage comprising a dithiocarbamate, a thiazole and a guanidine compound. In a preferred embodiment, the accelerator composition comprises zinc diethyldithiocarbamate (ZDEC), zinc 2-mercaptobenzothiazole (ZMBT) and diphenyl guanidine (DPG), in conjunction with a stabilizer, such as sodium caseinate. The invention also includes an elastomeric polyisoprene product made by the process, such as a surgeon's glove.

    摘要: The invention disclosed herein relates to an elastomeric article, such as a glove, containing an elastomeric material such as latex and a coating layer formed from an aqueous dispersion containing a composite of a silicone-modified polymer, e.g., a silicone-modified polyurethane, and silicone resin particles integrated therein. The interaction between the silicone groups on both the polymer and particles produces enhances binding effectiveness of the particles to the material. Gloves and other articles made in accordance with the invention contain a microroughened skin-contacting surface and exhibit a reduced coefficient of friction and increased lubricity, thereby enhancing the donning properties thereof.
