Abstract

Poly(L-lactide) (PLLA) is often regarded as tough and brittle while poly(1,3-trimethylene carbonate) (PTMC) is rather considered as a rubbery polymer. In an effort to improve the mechanical properties – especially ductility – of PLLA and thus to widen its field of applications, PLLA–PTMC diblock and triblock copolymers were synthesized through the sequential copolymerization of both L-lactide (L-LA) and trimethylene carbonate (TMC) using several catalytic systems. This process can be effectively catalyzed by inherently different systems ranging from a simple basic organocatalyst such as an amine (i.e., 4-N,N-dimethylaminopyridine, DMAP) or a phosphazene (i.e., 2-tert-butylimino-2-diethylamino-1,3-dimethylperhydro-1,3,2-diazaphosphorine, BEMP), a simple Lewis acidic metallic salt such as aluminum triflate, or a more sophisticated discrete metallo-organic complex derived from a biofriendly metal, namely the β-diiminate zinc complex [(BDIiPr)Zn(N(SiMe3)2)] (BDI = CH(CMeNC6H3-2,6-iPr2)2), [(BDIiPr)Zn(N(SiMe3)2)]. Well-defined diblock PLLA-b-PTMC, triblock PLLA-b-PTMC-b-PLLA and 3-arm star GLY(PTMC-b-PLLA)3 copolymers with controlled molecular features, i.e. controlled functional end-groups and molar masses, rather narrow dispersity values, were thus prepared. The thermo-mechanical properties of the resulting copolymers revealed that a minimal block size of the PTMC and of the PLLA segments within the copolymer of Mn,PTMC = ca. 10 000 g mol−1 and Mn,PLLA = ca. 23 000 g mol−1 enabl…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
