A new family of poss monomers suitable for forming urethane polymerizable nanocomposite coatings

摘要

Polyhedral Oligomeric Silsesquioxanes (POSS) are cage molecules consisting of an inner silicon-oxygen based framework with organic substiments on the outside. Novel octafunctional cubes with polymerizable moieties offer access to highly cross-linked (thermostat) nanocomposite coating materials which include desirable properties such as high heat distortion temperatures, toughness, abrasion and moisture resistance.
