Synthesis and properties of long-chain-branched poly(aryl ether sulfone)-poly(tetrahydrofuran) multiblock copolymers

Preparation and performance testing of novel bendable optically transparent fluorinated hyperbranched linear long chain segment poly(amide-imide) films

“…46 Moreover, long chain segments increase the polymer's chain entanglement, which improves the polymer's self-supporting ability and enhances the polymer's film-forming properties. 47,48 Lastly, it was found that the spatial configuration of the hyperbranched structure gives the polymer a low dielectric constant. 45 The aim of our current study is to improve the optical properties, such as the refractive index, transmittance, and chromaticity values, of polymer films.…”
