Title: Innovations by Ulrich Jansen: A Trailblazer in Graft Copolymer Technology

Introduction

Ulrich Jansen, a prominent inventor based in Dormagen, Germany, holds an impressive portfolio of 21 patents. His work primarily focuses on the development of graft copolymers, which are essential in various thermoplastic applications. Jansen's innovative processes contribute to enhancing the efficiency and quality of thermoplastic resin compositions.

Latest Patents

Among his latest patents, Jansen has developed a process for the production of graft copolymer powder compositions and thermoplastic resin compositions. This invention details a method for creating graft copolymer compositions based on acrylonitrile-styrene-acrylate (ASA) or acrylonitrile-butadiene-styrene (ABS) graft copolymers. The process involves emulsion polymerization, followed by precipitation, dewatering, drying, and optionally cooling the resulting graft copolymer powder. Notably, the graft copolymer B powder, which is aerated with gases like air and nitrogen, achieves a bulk density that is no more than 98.5% of the non-aerated powder throughout the aeration step. This innovation leads to enhanced powder flowability and reduces the occurrence of caking during storage.

Another significant patent is centered around the production of ABS graft copolymers, focusing on creating copolymers that dewater readily post-production. This process not only emphasizes reducing the residual moisture content after centrifugation but also highlights the effective production of thermoplastic molding materials derived from these ABS graft copolymers.
