Background Linear polyethylenimine (LPEI) with a molecular weight (MW) of 22 kDa has been described as having a superior ability to induce gene transfer compared to its branched form. However, the transfection efficiency of the polymer cannot be enhanced beyond a certain limit due to cytotoxicity. W

Solid-state thermal polymerization of isolated Bisphenol A type macrocyclic oligocarbonates was carried out. The ring-opening polymerization progressed without any catalyst. Dimer (c-2mer) could be completely converted to the corresponding aromatic polycarbonate by heating at 300 Β°C for 10 min. In c
## Abstract Lowβmolecular weight polyethylenimine (LMW PEI) shows the advantage of lowβcytotoxicity, but has been inefficient in gene delivery as a consequence of the lowβcharge density. A number of previous studies employed the approach of crosslinking to solve this problem. In this study, a starb
