Title: Jacques Poulenard: Innovator in Fluorinated Products and Waterproofing Technologies
Introduction
Jacques Poulenard is a notable inventor based in Lyons, France. He has made significant contributions to the field of materials science, particularly in the development of emulsions and waterproofing technologies. With a total of two patents to his name, Poulenard's work has implications for various industries, including textiles.
Latest Patents
One of Poulenard's latest patents focuses on emulsions of fluorinated products. This invention involves creating an emulsion of a fluorinated product in the presence of a derivative of morpholine. The derivative can be morpholine itself or its saturated and non-saturated derivatives, such as morpholinoethyl methacrylate. The fluorinated product may include a fluorinated monomer, specifically 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl methacrylate. The emulsion process is achieved by adding the morpholine derivative to the fluorinated product along with a surface-active agent, followed by mechanical stirring to achieve the desired liquid consistency.
Another significant patent by Poulenard involves a grafting process that ensures the waterproofing of polymeric materials. This process occurs after impregnating the polymeric material, which has been activated to create free radicals within an emulsion containing the fluorinated monomer and a graftable derivative of morpholine. The preferred reagents for this process are morpholinoethyl methacrylate and 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl methacrylate. This invention is particularly applicable to the waterproofing of textile articles made from materials such as cotton, silk, and linen. The grafted material remains waterproof when cold, while also allowing for washing, dyeing, or printing by transfer when heated.
