The article reports the effect of variation in the concentration of copper chloride on the elastic and viscoelastic properties of nylon‐6 films. The elastic modulus for the film is determined using sonic velocity measurement technique. The glass transition temperatures are determined from dynamic mechanical studies with the Rheovibron. It is observed that the glass transition temperature of the doped films increases with increase in the dopant concentration. It is also observed that at low concentrations of doping (up to 1.25%) the salt acts as a plasticizer, whereas for higher concentration of doping (up to 12.5%) it acts as an antiplasticizer.
