## Abstract Hydrogen bonding between N‐__t__‐butoxycarbonylproline N′‐methylamide and phenol derivatives (pK~a~ = 10.20–7.75) are investigated by ir and Fourier transform ir spectrometry. The thermodynamic parameters determined in carbon tetrachloride solution show that the complexes are of medium

## Abstract **Summary:** This paper reports an FT‐IR study of blends and complexes of poly(mono __n__‐alkyl itaconates) with poly(__N__,__N__‐dimethylacrylamide) (PDMA) and poly(ethyloxazoline) (PEOX). Strong hydrogen bonding has been found and both polybases have shown similar acceptor strengths.
