摘要：
Poly(L-lactic acid) and poly(D,L-lactic acid) samples have been synthesized through ring-opening polymerization. Studying homological series of two poly(lactic acids) by molecular hydrodynamics and optical methods has shown that poly-L-lactide chains in solution exhibit higher equilibrium rigidity than poly-D,L-lactide chains, which is explained by different chain tacticity.
