Abstract
AbstractStereoregular polyamides containing two chiral backbone carbons in the repeating unit were prepared by polycondensation of bis(pentachlorophenyl) 2,3‐O‐methylene‐L‐tartrate with 1,9 and 1,12‐alcanediamines activated as N,N′‐bis(trimethylsilyl) derivatives. The polymers were characterized by elemental analysis, IR, and 1H‐NMR spectroscopy, and differential scanning calorimetry. Both viscosimetry and GPC were used to estimate the molecular weights which ranged between 6000 and 44000. These polytartaramides were readily soluble in chloroform, displayed moderate optical activity in solution, and formed highly crystalline films.
