Title: Bruce H. Isaacs: Innovator in Polyurethane Technology

Introduction

Bruce H. Isaacs is a notable inventor based in Media, PA (US), recognized for his contributions to the field of polyurethane technology. He holds 2 patents that showcase his innovative approaches to improving chemical processes.

Latest Patents

One of his latest patents is titled "Process for rapid activation of double metal cyanide catalysts." This patent discloses a method for activating double metal cyanide catalysts by heating a polyol starter or starter/catalyst mixture under vacuum. This process achieves improved stripping compared to conventional vacuum stripping methods. By coupling vacuum stripping with inert gas sparging or using an organic solvent, the starter/catalyst mixture activates rapidly in an epoxide polymerization process. This rapid activation enhances the reliability of process start-ups and reduces cycle time, resulting in polyols with lower viscosity, lower polydispersity, and lower unsaturation, which are essential for producing better polyurethanes.

Another significant patent involves "Polyurethane elastomers exhibiting improved green strength while maintaining short demold times." This invention focuses on preparing elastomers from ultra-low unsaturation polyoxypropylene polyols that contain up to 20 weight percent internal random oxyethylene moieties. These elastomers demonstrate improved green strength and absorb less than 10 weight percent water at 0 degrees Celsius. The internal polyoxyethylene moiety-containing polyoxypropylene polyols can also be used to create haze-free 4,4'-MDI prepolymers, further enhancing elastomer processing.
