Patent
Highly branched polyphosphonates based on melamine
Bernhard Dr. Hess,Wolfgang Schulz-Schlitte,Juergen Dipl Chem Dr Kirsch,Dieter Dr. Freitag,Uwe Dr. Arndt,Hans Dipl Ing Gehrke,Klaus Zander +6 more
TL;DR: New, highly branched polyphosphonates which have a greatly improved flame retardant action compared with known polyphonates are suitable as additives for plastics as mentioned in this paper.
Patent
Process for the production of sheet metal/duroplast composite elements
Walter Uerdingen,Bert Dr Brassat,Karl-Ludwig Dipl Chem Dr Noble,Bernhard Dr. Hess,Heino Muller,Heinz Dipl Ing Eichner +5 more
TL;DR: The use of molding compositions based on unsaturated polyester resins containing specific reactive groups and of sheet metals with a specially selected coating results in sheet metal/duroplast composite elements having excellent adhesion.
Patent
Mixtures of polyurethanes and unsaturated polyester resins
Bernhard Dr. Hess,Hansjochen Dr Schulz-Walz,Hannes Von Dipl Chem Dr Harpe,Bernd Dr Peltzer,Ludwig Dr. Bottenbruch +4 more
TL;DR: Unaturated polyester resins containing polyesterurethanes having free carboxyl groups and/or terminal radically polymerizable double bonds are good starting materials for manufacturing moulded articles with outstanding properties, particularly with an excellent impact strength as mentioned in this paper.
Patent
Oxazolidone group-containing epoxy resins
Bernhard Dr. Hess,Hanns Peter Dr. Müller,Heinrich Dipl.-Ing. Heine,Bert Dr Brassat,Werner Prof. Dr. Klöker,Walter Dr. Uerdingen +5 more
TL;DR: In this paper, die Erfindung betrifft ein Verfahren zur Herstellung von oligomeren, Oxazolidongruppen, enthaltenden Polyepoxiden aus Bisepoxideiden und Diisocyanaten.
Patent
Stable organic dispersions which can be cured with little shrinkage, based on unsaturated polyester resins and thermoplastic polymers
Bernhard Dr. Hess,Karl Raichle,Ludwig Dr. Bottenbruch,Hansjochen Dr Schulz-Walz,Heinrich Dr. Alberts +4 more
TL;DR: The Disclosure Organic dispersions as mentioned in this paper can be cured with little shrinkage and are based on unsaturated polyester, copolymerisable vinyl or vinilydene compounds, thermoplastic polymers which are colloidally soluble and are incompatible with the polyester resin and an ethylene/vinyl acetate copolymers with high vinyl acetate contents show a good stability.
