Title: Innovations of Hans-Dieter Hermann
Introduction
Hans-Dieter Hermann is a notable inventor based in Bad Soden am Taunus, Germany. He has made significant contributions to the field of polymer chemistry, particularly in the development of graft polymers. With a total of 2 patents, his work has implications for various applications in coating compositions and thermoplastically processable materials.
Latest Patents
Hermann's latest patents focus on graft polymers containing polyvinyl acetal groups on polyurethane. These polymers are characterized by acetalized polyvinyl alcohol groups that are prepared from graft polymers containing vinyl alcohol groups. The process involves the reaction with aldehydes, which can be any known aldehydes capable of acetalization reactions. The polyurethane grafting substrates used in these patents contain at least two urethane groups and units from diisocyanates and diols. The polymers also include polymer radicals of vinyl carboxylates and their hydrolysis products. The proportion of vinyl alcohol units in the hydrolyzed graft polymers is greater than 10% by weight, and the acetalized polymer retains a content of residual unacetalized vinyl alcohol units greater than 7.5 mol%. These graft polyvinyl acetals are versatile and can be used in coating compositions, as coating agents for diverse substrates, and as materials for thermoplastically processable moldings.
