Title: Cornelis Den Doelder: Innovator in Polymerization Processes

Introduction

Cornelis Den Doelder is a notable inventor based in Terneuzen, Netherlands. He has made significant contributions to the field of polymerization, particularly in the development of low-density polyethylene. With a total of 2 patents to his name, Den Doelder's work has had a considerable impact on the industry.

Latest Patents

One of his latest patents involves a high-pressure polymerization process to form an ethylene-based polymer. This innovative process includes several steps: First, a feed comprising ethylene and a chain transfer agent system is injected into a first autoclave reactor zone operating under specific polymerization conditions. This produces a first zone reaction product. The process continues with the transfer of at least part of this product to a second reactor zone, which may be either a second autoclave reactor zone or a tubular reactor zone. The second reactor zone also operates under polymerization conditions and may involve the injection of a second feed. A critical aspect of this process is the ratio of the transfer activities of the chain transfer agent systems in both reactor zones.
