Title: Innovations by Riaz Ahmad Choudhery in Coating Technologies
Introduction
Riaz Ahmad Choudhery, based in Solihull, GB, is a prominent inventor known for his contributions in the field of coating technologies. With a remarkable portfolio consisting of 15 patents, Choudhery has made significant advancements in the preparation of organic solvent-based dispersions and aqueous polymer dispersions.
Latest Patents
Choudhery's latest patents include a groundbreaking process for preparing organic solvent-based dispersions. This invention involves a method to create a melt-blended network of epoxy-functional and/or amino-functional polymers, which are crucial in developing coating compositions for packaging applications. The detailed process consists of several steps: first, forming the melt-blended network from a prepolymer, a silane-functional compound, and a polyolefin (co)polymer in the absence of a solvent. This is followed by mixing the network with an organic solvent and subsequently cooling the dispersion.
Another notable patent focuses on producing aqueous polymer dispersions. This process involves creating a stable dispersion of at least two preformed polymers, each modified by grafted addition polymers. The method includes providing a solution in an organic carrier liquid of a first preformed polymer, mixing it with ethylenically unsaturated monomers, and polymerizing and grafting these monomers to the preformed polymers to form a solution of modified polymers.
