AB  - Poly(ethylene terephthalate) (PET) substrates were modified by means of 
      surface-initiated supplemental activator and reducing agent atom transfer radical 
      polymerization (SI-SARA-ATRP) of 4-vinylpyridine (4VP). Substrates were 
      pretreated in order to graft chloromethylbenzene (CMB) units capable of 
      initiating the radical polymerization reaction of 4VP units. Surface 
      characterization techniques, including Water Contact Angle (WCA), Attenuated 
      Total Reflection (ATR), X-ray photoelectron spectroscopy (XPS), Atomic Force 
      Microscopy (AFM) and Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) 
      showed a successful grafting of a stable, smooth and homogenous layer of p4VP. 
      This process offers the advantages of a rapid, simplified and low cost strategy 
      to chemically modify polymer substrates with covalently bonded layer of the pH 
      responsive p4VP for different applications. Moreover, by using TOF-SIMS 
      profiling, we were able to track a density gradient along the z-axis generated by 
      the interpenetrating phases of the different layers of the final modified 
      surface. Fact that we correlated to the various positions of initiation sites 
      within the polyethylenimine (PEI) used for PET aminolysis prior to CMB grafting. 
      Our strategy will be used in future work to graft other polymers for different 
      applications where industrial scale viable options are needed.
