Title: Innovations by Inventor Shruti Singhal
Introduction
Shruti Singhal is a prominent inventor based in Conshohocken, PA (US). She has made significant contributions to the field of polymer chemistry, holding three patents that showcase her innovative approach to resin production.
Latest Patents
One of her latest patents is for a solid acrylic resin using a continuous tube reactor. This process involves creating acrylic resins that serve as polymeric surfactants for emulsion polymerization, pigment grinding resins, and dispersions for overprint varnishes. The feedstock includes styrene, α-methyl styrene, acrylic acid, and a polymerization initiator, ideally without solvent. The mixture is processed through a continuous tube reactor under controlled pressure, low residence time, and temperature. The recovered monomers from the devolatilization process are reused in the feedstock.
Another notable patent is for a continuous bulk polymerization process. This invention outlines a method for producing a polymer or copolymer from acrylate and methacrylate monomers. The process involves charging a continuous tube reactor with the monomer material and a polymerization initiator, maintaining a specific flow rate and reaction temperature to ensure polymerization occurs. The resulting resin product, which contains unreacted monomers, is devolatilized to yield a substantially monomer-free resin. This resin is particularly valuable as an additive for coating and casting resin systems, with a weight average molecular weight of 10,000 or less and a glass transition temperature below 0°C.
Career Highlights
Throughout her career, Shruti has worked with notable companies such as Cook Composites & Polymers Company and Cognis Corporation. Her experience in these organizations has contributed to her expertise in polymer chemistry and innovation.
Collaborations
Some of her coworkers include George Roth and George A. Smith, who have collaborated with her on various projects in the field of polymer research.
Conclusion
Shruti Singhal's contributions to polymer chemistry through her innovative patents and career highlights demonstrate her significant impact in the field. Her work continues to influence the development of advanced resin products.
