dc.description.abstract | In this study, we report the acid-catalyzed and high pressure assisted ring-opening polymerization (ROP) of
g-butyrolactone (GBL). The use of a dually-catalyzed approach combining an external physical factor and
internal catalyst (trifluoromethanesulfonic acid (TfOH) or p-toluenesulfonic acid (PTSA)) enforced ROP of
GBL, which is considered as hardly polymerizable monomer still remaining a challenge for the modern
polymer chemistry. The experiments performed at various thermodynamic conditions (T ¼ 278–323 K
and p ¼ 700–1500 MPa) clearly showed that the high pressure supported polymerization process led to
obtaining well-defined macromolecules of better parameters (Mn ¼ 2200–9700 g mol 1; Đ ¼ 1.05–1.46)
than those previously reported. Furthermore, the parabolic-like dependence of both the molecular
weight (MW) and the yield of obtained polymers on variation in temperature and pressure at either
isobaric or isothermal conditions was also noticed, allowing the determination of optimal conditions for
the polymerization process. However, most importantly, this strategy allowed to significantly reduce the
reaction time (just 3 h at room temperature) and increase the yield of obtained polymers (up to 0.62
gPGBL/gGBL). Moreover, despite using a strongly acidic catalyst, synthesized polymers remained non-toxic
and biocompatible, as proven by the cytotoxicity test we performed in further analysis. Additional
investigation (including MALDI-TOF measurements) showed that the catalyst selection affected not only
MW and yield but also the linear/cyclic form content in obtained macromolecules. These findings show
the way to tune the properties of PGBL and obtain polymer suitable for application in the biomedical
industry. | pl_PL |
