Title: The Innovations of John S. Currie: Pioneering Silicone Polymer Production

Introduction

John S. Currie, an accomplished inventor based in Penarth, GB, has made significant contributions to the field of polymer chemistry. With a total of four patents to his name, he has played a vital role in developing innovative processes that enhance the production of silicone polymers.

Latest Patents

Among his notable inventions, Currie's latest patents focus on a continuous process for producing silicone polymers. This process involves a series of sequential steps. The first step includes the polymerization of a linear silanol group containing siloxane via condensation polymerization or utilizing a cyclosiloxane through ring-opening polymerization. This step can also incorporate a mixture of linear and cyclosiloxanes with a phosphazene base, in the presence of water and, optionally, a filler within an extruder.

The second step is the neutralization of the reaction mixture, accomplished in an extruder. The final step involves stripping the neutralized reaction mixture in order to eliminate volatile materials. Notably, Currie emphasizes efficiency by performing all three steps within a single extruder.

In his second recent patent on the same subject, Currie adopts a slightly different approach. He outlines a similar continuous process for producing silicone polymer, where the neutralization can occur in a static mixer or in-line mixer, in addition to an extruder. Again, the stripping of the neutralized reaction mixture aims to remove volatile materials, showcasing his innovative problem-solving skills in polymer production.
