Title: Daniel Mark Henn - Innovator in Papermaking Additives
Introduction
Daniel Mark Henn is an inventor based in Wilmington, DE (US). He has made significant contributions to the field of papermaking through his innovative approaches to additive compositions. Although he currently holds no granted patents, his work in developing new materials for the papermaking process is noteworthy.
Latest Patent Applications
Henn's latest patent applications include "ADDITIVE COMPOSITIONS FOR PAPERMAKING," which discloses a drainage-optimized additive composition. This composition comprises an aqueous media, a glyoxalated polyacrylamide (GPAM) resin, and an anionic polyacrylamide (APAM) resin. The GPAM resin has a weight average molecular weight (Mw) of at least about 5 MDa and a cationic monomer content of at least about 4 mol %. The APAM resin has a Mw of at least about 0.25 MDa, and an anionic monomer content up to about 25 mol %. The method of preparing this additive composition can be carried out in situ during the papermaking process.
Another application is titled "ADDITIVES AND COMPOSITIONS FOR PAPERMAKING," which discloses a cationic polyacrylamide (cPAM) and methods of making and using the same. The cPAM comprises the radical polymerization reaction product of an acrylamide (AM) monomer, a cationic monomer, and optionally, one or more additional ethylenically unsaturated monomer(s). A glyoxalated polyacrylamide (gPAM) resin is also disclosed, which comprises the reaction product of a glyoxalation agent and the cationic polyacrylamide (cPAM). The additive composition for papermaking includes an aqueous media and the glyoxalated polyacrylamide (gPAM) resin dispersed therein.
Conclusion
Daniel Mark Henn's innovative work in papermaking additives showcases his commitment to advancing the industry. His latest patent applications reflect a focus on improving the efficiency and effectiveness of papermaking processes.
