Functionalization of polymers prepared by “living” free radical polymerization

Nitroxide- and bromo-terminated polystyrenes resulting from “living” free radical polymerization processes have been “functionalized” by combination reaction with thiuram disulfides compounds i.e. tetraethyl thiuram disulfide and N,N’-diethyl-N,N’-bis{2-(trimethyisilyloxy)ethyl} thiuram disulfide, or tetraphenylethane based derivatives i.e. 1,1,2,2-tetraphenyl-1,2-bis(trimethyl-silyloxy)ethane. The substitution of the terminal moiety by dithiocarbamate or diphenylmethyl groups have been characterized by ¹H NMR, ¹³C NMR, IR spectroscopy, MALDI-TOF mass spectrometry, ESI mass spectrometry and LSI mass spectrometry.
