Title: The Innovative Contributions of Charlotta Kanto Oeqvist

Introduction

Charlotta Kanto Oeqvist is a notable inventor based in Kempen, Germany. She has made significant contributions to the field of polymer chemistry, particularly in the development of novel emulsion polymers. With a total of 2 patents, her work has implications in various industrial applications, especially in papermaking.

Latest Patents

Oeqvist's latest patents include the invention of a bimolecular inverse emulsion polymer. This invention relates to stable bi-molecular cationic inverse emulsion polymers (W/O) that possess different molecular weights and cationic activities. These polymers are assembled through an 'in situ' emulsion polymerization process, which involves a high molecular weight cationic polymer in the presence of a low molecular weight polymer in the aqueous phase. The low molecular cationic polymer is produced in a pre-polymerization in solution. This novel cationic water-in-oil emulsion is easily invertible and serves as a useful flocculant, dewatering aid, and retention aid in papermaking.

Another significant patent involves cationic cross-linked polymers in water-in-water polymer dispersions. This invention focuses on water-in-water polymer dispersions that contain cross-linked cationic polymers, along with methods for their preparation and use. These dispersions are particularly useful as flocculants, dewatering aids, and retention aids in the papermaking industry.
