With a total of 7 patents to his name, Grundmann's work has had a lasting impact on various industries.
Latest Patents
One of Grundmann's latest patents is a process for producing bromomethylated polyphenylene ethers. This innovative method involves reacting polyphenylene ethers, especially poly(2,6-dimethyl-1,4-phenylene) ether, with formaldehyde and hydrogen bromide in the presence of carboxylic acids. The result is a product that contains up to 37.6% by weight of bromine and demonstrates a weight loss of 2-40% by thermogravimetric analysis at temperatures between 250°C and 325°C. These bromomethylated polyphenylene ethers are particularly suitable as flame retardants. Another significant patent focuses on fire retardant damping materials based on polyvinyl chloride. This invention introduces new lightweight damping materials made from polyvinyl chloride particles or balled-up fibers, which have a bulk density of 10-200 g/l and a particle weight of less than 1 g. These materials can be combined into lightweight components using heat or binders, such as adhesives or curable polymers.
