Kevlar; liquid crystalline polymers

1985 patented a method for preparing PBO & PBT polymers; researched aramides (aromatic polyamides-a polymer that can be made into strong stiff & flame-resistant fabric; wrote the Nylon Rope Trick-demonstrating how to produce nylon fiber in a beaker at room temperature an experiment that continues to be used in H.S. chemistry classes; discovered a new branch of synthetics liquid crystalline polymers & prepared the first pure monomers used to synthesize polybenzamide; invented Kevlar; holds 29 patents
