Dimethyl L-tartarate underwent polycondensation reaction with hexamethylenediamine in solutions at 30°C to form polyamide having pendent hydroxyl groups. Solvents had a great influence on polymer yields and diglyme, tetrahydrofuran (THF) or dimethylsulfoxide (DMSO) were favorable in respect of polymer yields. Solution viscosities of resulting polyamide were as low as 0.1 to 0.2. However, post-polycondensation of the precursor polyamide at solid phase yielded hydrophilic polyamide having film-forming ability. The polyamide decomposed at 210°C by heating.
