Title: Swarup Kumar Maiti: Innovator in Modified Lignin Products

Introduction

Swarup Kumar Maiti is a notable inventor based in Pittsburg, Kansas, who has made significant contributions to the field of polymer engineering. He holds 2 patents that focus on the development of modified lignin products for rigid foams. His innovative work has implications for improving the performance and sustainability of polyurethane and polyisocyanurate foams.

Latest Patents

Maiti's latest patents detail processes for creating modified lignin products that enhance the properties of rigid foams. The processes involve heating a lignin source with a nitrogen source and a starved concentration of a C-Caldehyde, resulting in a reaction mixture that includes a Mannich condensation product. The reaction mixture is then neutralized, and the modified lignin product is isolated. The process is optimized with a mass ratio of lignin source to nitrogen source ranging from 1:1 to 1:5, and a molar ratio of nitrogen source to C-Caldehyde between 3.5:1 and 1:1. The resulting polyol blends and performance additives containing these modified lignin products demonstrate excellent flame retardancy and low-temperature R-value performance, with the ability to incorporate up to 60 wt. % of the modified lignin based on the polyol component.
