Title: Maurice Charpenel: Innovator in Biodegradable Materials
Introduction
Maurice Charpenel is a notable inventor based in Lyons, France. He has made significant contributions to the field of biodegradable materials, holding 2 patents that reflect his innovative spirit and dedication to sustainable solutions.
Latest Patents
Charpenel's latest patents include groundbreaking work on detersive polyanhydroaspartic acids and biodegradable hydrolysates. These novel polyanhydroaspartic acids are designed to contain no more than 3% of NH groups of the imide moieties relative to the total amount of CH moieties of the succinimide moieties. They are well-suited as detergent (co)builders and are prepared by thermally polymerizing aspartic acid in the presence of a boron compound. The biodegradable hydrolysates derived from these acids contain no more than 3% of primary amide groups relative to the secondary amide groups of the aspartic moieties.
Another significant patent involves boron/nitrogen preceramic polymers and boron nitride ceramic materials. These organometallic boron/nitrogen polymers are created by reacting trihalogenoborane with silazane compounds containing .tbd.Si--NH--Si.tbd. groups. The resulting organometallic polymers can be pyrolyzed into boron nitride ceramic materials, showcasing Charpenel's innovative approach to material science.
