The imide ring-opening reaction by the attack of amino groups occurs because of the coexistence of primary amino compounds with the imide ring.
The wettability of paper surfaces with adsorbed nanoparticles can be controlled by tuning the chemical and topographical surface parameters: the water contact angles were found to increase at higher imide content as determined by Raman spectroscopy (depending on synthesis and thermal treatment), and higher average surface roughness determined by AFM (depending on the deposition method).
1] These polymers are characterized by their thermal and mechanical stability [2] due to presence of rigid imide ring in the back bone.
The film comprises a thermoplastic resin with a substituted or non-substituted imide group at a side chain of the resin and a thermoplastic resin with a substituted or non-substituted phenyl group and a nitrile group at a side chain of the resin.
Relatively inexpensive, SMA imide resins can be dissolved easily and can be used in the headbox.
This yields a product containing a tough imide bond--similar to the rigid linkage that makes the polymer Kevlar strong enough to serve in bulletproof vests.
Limited Tenders are invited for Polyether imide pellets - 10 kgs.
It is notable that BPOB-5 has higher orientation than BPOB-1, which can be explained by the fact that hydrogen bonding between the BIA and cyclic imide units restricts the flexibility of the polymer chain and the disorientation.
Sartomer Company has announced the commercial availability of its line of styrene maleic anhydride (SMA[R]) imide resins, a group of multi-functional cationic additives that impart performance properties during the wet end and paper coating stages of paper manufacturing.
