Enhancement of the high‐temperature properties of an SEBS thermoplastic elastomer by chemical modification

Journal of Applied Polymer Science (Impact Factor: 1.4). 08/2002; 86(5):1203 - 1210. DOI: 10.1002/app.11065

ABSTRACT A procedure was developed for benzoylating the polystyrene segments in polystyrene-b-poly(ethylene-co-butene)-b-polystyrene (SEBS) triblock copolymers. The products were characterized by NMR spectroscopy, gel permeation chromatography, dynamic mechanical thermal analysis, and membrane osmometry. The mechanical properties of the parent and benzoylated copolymers, measured from 25 to 150°C, indicated that benzoylation increases the utility of the polymers at elevated temperatures. © 2002 Wiley Periodicals, Inc.
