Summary
Polybutyleneterephthalate (PBTP) has been labelled both in solution and in solid state with 3-chloroformyl-2,2,5,5-tetramethylpyrroline-1-oxyl. The reaction with PBTP in solution can be used to determine the hydroxyl end-groups. The differences observed in the spin-labelling of the polymer in solution and in solid state are discussed.
