Improving the stability of polymers against the effects of heat and flames by addition of a pyrogenic titanium dioxide having a BET surface area of greater than 50 m2/g to the polymer prior to or during polymer processing

摘要

A process for improving the stability of polymers against the effects of heat and flames comprises the addition of a pyrogenic titanium dioxide having a BET surface area of greater than 50 m2/g to the polymer prior to or during polymer processing.
