for the formation of hyperbranched polyimides accordingly the resulting hbpis were analyzed by gpc indicating the molecule weights of 5000 u02dc 7000 g mol with a distribution of polydispersity between 2 0 and 3 8 the amine titration for hbpis indicated the peripheral total amine contents to be 8 32 u02dc 18 32 mequiv g dependent on compositions application_number US 201213714150 A description u201c 2d layered material u201d is the material such as montmorillonite synthetic fluorinated mica layered double hydroxides ldhs and the like which can be ion exchanged through an inorganic intercalating agent allowing monomers to flow in or out such that the interlayered spacing can be increased from 10 u00e5 to approximately 20 u02dc 30 u00e5 u201c intercalation u201d indicates substances dispersed regularly between layers that are separated by a specific spacing which means organic molecules intercalate between layers to avoid the interaction between layers and restacking behavior u201c exfoliation u201d indicates that every single layer exists in an irregular distance and orientation it can be normally achieved by an organic intercalating agent to increase the interlayered spacing to a specific extent which increases the affinity between inorganic layers and the organic polymer and then the organic inorganic polymeric nanocomposites can be obtained through polymerization compounding technology.
