In this work we have studied the synthesis in solution of different po
livinyl pyrrolidone/copper complexes (PVP/Cu) using distillate water a
s solvent. The study has been focused on the interactions established
between the polivinyl pyrrolidone and the metal cation Cu2+ at 298 and
338 K at different copper concentration using four different PVP mola
r mass samples. We have employed viscometry as the the experimental te
chnique.
