Two new stereoregular polyamides, namely PTA-LL and PTA-LD, derived from (2S,3S)-(Ϫ)-2,3-dimethoxy-1,4-butanediamine and (2R,3R)-(ϩ)-or (2S,3S)-(Ϫ)-2,3-dimethoxybutanedioic acid are described. The two diastereoisomeric polymers contain two pairs of stereocenters in the main chain of the repeating un
