Title: **Richard L. Donald: Innovator in Rigid Foam Production**

Introduction

Richard L. Donald is a notable inventor based in Meridian, MS, with an impressive portfolio of six patents. His contributions to the field of polyurethane and thermosetting foam technologies showcase his eagerness to enhance materials for various applications. Donald's innovative methods of producing rigid foams have the potential to revolutionize industries reliant on these materials.

Latest Patents

Among Richard L. Donald's latest patents is a groundbreaking method of producing polyurethane modified polyisocyanurate foam. This method utilizes at least one alkali metal organo-salt catalyst in an aqueous solution that is free of aliphatic glycols. The preferred catalyst has more chemical equivalents of at least one carboxylic acid than those of at least one alkali metal hydroxide dissolved in water. This approach not only generates flame-resistant amides but also employs carbon dioxide as a blowing agent while reducing overall water content.

Additionally, Donald developed another method to produce a thermosetting foam through a two-blend process. The first blend, known as the A-Blend, is prepared using a multi-functional isocyanate, while the second blend (B-Blend) consists of various components including polyol, water, and a tertiary amine catalyst. The innovative aspect lies in the catalyst's capability to initiate a rapid reaction between polymeric polymethylene polyphenylisocyanate and water, which contributes to a quick foam expansion process before the solidification occurs, enabling better foam quality.
