Synthesis of 1,1-dihydroperfluorooxaalkan-1-ols and their interaction with terephthaloyl chloride

Fluorinated Polyurethanes, Synthesis and Properties

“…Bp of the products was above 200 °C (0.01 Torr). They were prepared according to the procedure reported in [24] and represent fluoropolyether glycols or fluoropolyether amides containing hydroxymethylated terminal groups ( 1a – b ) or a mixture of fluoropolyether glycols with alcohols of similar structure ( 1c – d ) with ratio 7:1. Molecular weights and compositions of the prepared fluoropolyether diols and alcohols were found from 19 F-NMR and 1 H-NMR data.…”
