ABSTRACT:
The invention relates to the chemical bonding of a polymer/or polymers onto non-metallic substrates such as cellophane by ultrasonic techniques. The cellophane film is preactivated by contacting with silver nitrate solution followed by treatment with potassium hydroxide solution whereby particles of silver and silver oxide are uniformly distributed, in situ, over the surface of cellophane film. The pretreated cellophane film when contacted with grafting solution, that contains monomers, prepolymers, catalyst, graft initiator and other ingredients of the composition, which is being agitated with ultrasonic energy results in polymerization of monomer/prepolymer onto the surface of the cellophane film.
