Abstract:
Perfluoroalkyl substituted neopentyl alcohols can be reacted with substituted hydroxphenylalkanoic esters to form perfluoroalkyl containing hydroxyphenylalkanoic ester antioxidants. The perfluoroalkyl substituted hindered hydroxyphenyl alkanoates are stablizers which confer superior processing stability to polymers processed at elevated temperatures such as polypropylene, as well as protecting said polymers from thermal and oxidative degradation.
