Latest Patents
Siegfried Schiller's latest patents include innovative processes for preparing copolymers of ethylene with acrylic esters. The first patent describes a method for copolymerizing 100 parts by weight of ethylene with from 0.1 to 25.0 parts by weight of acrylic ester in a continuous tubular polymerization system. This process operates at pressures ranging from 500 to 4000 bar and temperatures between 100°C to 400°C, utilizing free radical polymerization initiators. The key aspect of this invention is the control of the temperature increase per unit time, maintaining a constant ratio of dT/dt between 1.5°C to 2.5°C per second.
The second patent focuses on the preparation of copolymers of ethylene with acrylates or acrylic acid. In this process, 100 parts by weight of ethylene are copolymerized with from 1.0 to 20.0 parts by weight of tert-butyl acrylate, tert-butyl methacrylate, or acrylic acid. This method is conducted in a continuously operated tubular polymerization system at pressures above 800 bar and temperatures from 130°C to 320°C. The process involves feeding two gas streams into the polymerization system, ensuring efficient copolymerization.
