✦ Synopsis

The reaction of (R,R)-trans-1,2-bis (2,4,6-triisopropylbenzenesulfonamidato)

Experimental results show that all three complexes 2e4 are active toward the ring-opening polymerization of L-lactide and compound 2 efficiently catalyzes the polymerization of L-lactide in the presence of a variety of alcohols in a controlled fashion with very narrow polydispersity index. In addition, a variety of biodegradable poly(L-lactide)-block-poly(N x -carbobenzyloxy-L-lysine) block copolymers with different ratios have also been synthesized using poly(L-lactide) containing amino chain end (PLLA-NH 2 ) as a macroinitiator.

## Abstract Summary: In situ self‐assemblies of new biodegradable triblock PLLA‐__b__‐PBS‐__b__‐PLLA and PDLA‐__b__‐PBS‐__b__‐PDLA have been investigated in acetonitrile solution. At first, two series of PLLA‐__b__‐PBS‐__b__‐PLLA and PDLA‐__b__‐PBS‐__b__‐PDLA, respectively denoted as the P and Q tr

## Abstract Diblock and triblock copolymers were prepared from polyethylene glycol (PEG, $\overline M \_{\rm n}$ = 2 000), L‐lactide and D,L‐lactide. A novel method was developed to prepare high‐molecular‐weight multiblock copolymers by transesterification of a PEG/succinic acid polyester with poly
