Title: Jerold C. Rosenfeld: Innovator in Polyimide Technology

Introduction

Jerold C. Rosenfeld, based in Tonawanda, NY, has made significant contributions to the field of polymer chemistry, particularly with a focus on polyimides. With a remarkable total of 19 patents to his name, Rosenfeld's innovations have played a vital role in the development of advanced adhesive materials and polymers.

Latest Patents

Among his latest patents is a revolutionary polyimidesiloxane adhesive. This adhesive is created by reacting a dianhydride, specifically either biphenyl dianhydride or oxydiphthalic anhydride, with a stoichiometric amount of a diamine. Notably, this diamine mixture incorporates approximately 5 to 30 mole % of a siloxane-containing diamine along with 70 to 95 mole % of a non-siloxane diamine. The non-siloxane portion includes various diamines such as 2,2-bis(4-[4-aminophenoxy]phenyl) propane and 3,3'-diaminophenylsulfone, allowing the adhesive to be adaptable to multiple formats like one, two, and three-layer tapes, characterized by high temperature resistance and low bonding temperatures.

Another significant patent from Rosenfeld involves the method of creating imide-containing polymers through bulk or melt polymerization. This method utilizes a mixture comprising a cyclic compound with an anhydride group and a diamine, maintaining precision in stoichiometric calculations. Heat is then applied to polymerize the mixture without the use of solvents, providing a scalable and efficient approach to polymer production.
