The crystallization, morphology, and stereocomplexation of amphiphilic poly(D-lactide)-b-poly(N,N-dimethylamino-2-ethyl methacrylate) (PDLA-b-PDMAEMA) and poly(L-lactide)-b-poly(N,N-dimethylamino-2-ethyl methacrylate) (PLLA-b-PDMAEMA) copolymers were studied and compared to those of the corresponding poly(lactide) homopolymers. The crystallization kinetics of the PLA blocks was retarded by the presence of the PDMAEMA block. The melting points of PLDA/PLLA and PLA/PLA-b-PDMAEMA stereocomplexes were higher than those formed by copolymer mixtures indicating that the PDMAEMA block is influencing the stability of the stereocomplex structures.
