Title: Tarja Ikävalko: Inventor in Cellulose Chemistry
Introduction
Tarja Ikävalko is an inventor based in Espoo, Finland, and is associated with Kemira Oyj. Her patent work concerns the production of cationized cellulose, a chemically modified cellulose material.
Latest Patents
Ikävalko is named on one patent, titled “Method for Producing Cationized Cellulose and Cationized Cellulose.” The invention describes preparing a concentrated slurry of cellulosic starting material in an alkaline liquid medium containing an organic liquid, then mercerizing the slurry. After mercerization, a cationizing agent is added at a temperature below the medium’s boiling point, allowing the cellulose to react and form a cationized cellulose product. The process may be carried out under an inert atmosphere. Ikävalko is credited with 1 patent.
Career Highlights
The patent reflects work on a process for modifying cellulose through cationization. Its described steps include using a high concentration of cellulosic starting material and adding the cationizing agent after mercerization.
Collaborations
Ikävalko’s listed coworkers include Veli-Matti Vuorenpalo and Jonni Ahlgren. Her patent is associated with Kemira Oyj.
Conclusion
Tarja Ikävalko’s patent contribution focuses on a method for producing cationized cellulose through controlled slurry preparation, mercerization, and reaction with a cationizing agent.
