Title: Innovations of Johannes L Syrier

Introduction

Johannes L Syrier is a prominent inventor based in Amsterdam, Netherlands. He has made significant contributions to the field of polymer chemistry, particularly in the development of stabilized copolymers. With a total of 18 patents to his name, Syrier's work has had a substantial impact on the industry.

Latest Patents

Among his latest patents, Syrier has developed stabilized olefin/carbon monoxide copolymers. These linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon are stabilized against thermal degradation by the inclusion of certain phenolic compounds. Additionally, he has created stabilized copolymer compositions that comprise a major amount of an alternating copolymer of carbon monoxide with one or more olefinically unsaturated compounds. This composition includes a minor amount of at least one stabilizing additive, which is a zeolite-type trivalent-metal silicate containing a cation of an element of Group 2 of the Periodic Table. This copolymer composition exhibits improved stability and contains a substantially reduced amount of residual solvent. Furthermore, he has disclosed a process for producing this copolymer composition and articles of manufacture made from it.
