Title: The Innovative Contributions of Henry Gisser

Introduction

Henry Gisser is a notable inventor based in Philadelphia, PA (US). He has made significant contributions to the field of polymer chemistry, holding a total of 6 patents. His work primarily focuses on the development of novel copolymers that enhance material properties.

Latest Patents

One of Gisser's latest patents involves copolymers of alpha-n-alkylstyrenes and styrene. This invention describes novel copolymers that contain at least eleven carbon atoms in the alkyl group. The copolymers, which consist of at least 20 mole percent of the alpha-n-alkylstyrenes, are solids that exhibit greater durability and lower coefficients of friction compared to traditional styrene homopolymers. These copolymers are produced through anionic initiated copolymerization using metallic sodium as the catalyst or by radical initiated copolymerization using benzoyl peroxide or azobisisobutyronitrile as the catalyst. Another significant patent involves anionically polymerized copolymers of methyl alpha-n-alkylacrylate, formed by reacting methyl methacrylate and methyl alpha-n-alkylacrylate at temperatures between 20°C and 30°C in the presence of catalytic amounts of sodium, where the alkyl group in the methyl alpha-n-alkylacrylate contains between 10 to 22 carbon atoms.
