**4. Conclusions**

The FTIR-ATR technique makes it possible to examine polymers in a simple, fast procedure avoiding sample destruction. It creates many opportunities for application to the chemical identification of the surface layer of polymers and thin polymeric layers. The analyses of test results of thin layers deposited on polymeric substrates can have rather qualitative character due to the penetration reach of the IR radiation beam being greater than the layer thickness. The examples of PP modification processes and deposition of coatings on polymeric substrates presented confirm that the FTIR-ATR method can be helpful in the examinations of the following:
