Synthesis and gas permeation properties of hyperbranched polyimides membranes from a novel (A2+B2B′+B2)-type method

Microencapsulation of quinoline as a corrosion inhibitor in polyurea microcapsules for application in anticorrosive PU coatings

“…Dendritic and hyperbranched polymers are a new class of polymers with terminal multi-functionality and have received a great deal of attention from many research groups [16][17][18]. It is reported that these macromolecules have been found to be effective to toughen thermosetting polymers such as epoxies and urea formaldehyde [19,20].…”

Effects of crosslinking agents on the physical properties of polyimide/amino‐functionalized graphene oxide hybrid films

“…Thus, with an increasing in the contents of TAP and melamine crosslinkers, the molecular weights would be decreased. The lower molecular weights promote segmental motion at lower temperatures and lead to the lower T g values …”

Synthesis and characterization of branched phenylethynyl-terminated polyimides

“…2. The corresponding chemical shift of hydrogen atoms in DMSO-d 6 is shown in Table 2 [27]. 1 H NMR spectra of neat PI and BPIs are shown in Fig.…”

“…However, to further extend the application of polyimides as in high-performance advanced polymeric composites, it is anxiously fabricating new kinds of PETIs with much better processability. Recently, dendrimers and hyperbranched polymers have been attracting significant attention, owing to their relatively low viscosity and excellent solubility in organic solvents [23][24][25][26][27]. However, it is well known that many hyperbranched polymers exhibit poor mechanical properties.…”
