Title: The Innovative Works of Dieter Woltjes

Introduction

Dieter Woltjes, an inventor based in Dormagen, Germany, is recognized for his significant contributions to the field of polymer chemistry. With a total of two patents to his name, Woltjes has developed innovative solutions that enhance the performance and application of paint resins in powder coating.

Latest Patents

One of Woltjes’s recent patents is focused on a novel paint resin designed specifically for powder coating. This resin is characterized by its composition of modified high-pressure polyethylene (LDPE) and ionomer-modified polyethylene as the film material. The invention details a process of creating ionomer-modified polyethylene—an ethylene/carboxylic acid copolymer—wherein at least a portion of the acidic groups are neutralized. This is achieved through a one-stage procedure involving the reaction of ethylene with unsaturated carboxylic acids and their salts, in the presence of a free radical polymerization initiator, under conditions typical for high-pressure polyethylene production. Notably, the concentration of salt added to the polymer is limited to a maximum of 1 mol%, relative to the converted ethylene and other comonomers. The process results in ionomer-modified polyethylenes suitable as film material, boasting high strength, excellent drawability, and remarkable tear propagation resistance.
