Perry, Robert J.; Turner, S. Richard; Blevins, Richard W. published the artcile< Palladium-Catalyzed Formation of Poly(imide-amides). 2. Reactions with Chloroiodophthalimides and Diamines>, Application In Synthesis of 118-45-6, the main research area is palladium catalyst polymerization chlorophthalimide aromatic diamine; iodine catalyst preparation polyimide polyamide.
High-mol.-weight poly(imide-amides) can be readily formed by the Pd-mediated carbonylation and condensation reactions of activated chlorophthalimide monomers and aromatic diamines. The presence of iodide ion greatly accelerates the rate of reaction and increases the ultimate mol. weight of the polymer. Polymerizations proceed best using a protocol of high CO pressure (90 psig) for 2-4 h, followed by lower CO pressure (20 psi) in DMAc or NMP for 24-48 h at 100° using 0.3-3.0% PdCl2L2 (L = PPh3) as the catalyst with 2-6 equiv of PPh3/Pd and 0.3-1.0 equiv of an iodide/chloro group.
Macromolecules published new progress about Glass transition temperature. 118-45-6 belongs to class chlorides-buliding-blocks, and the molecular formula is C8H3ClO3, Application In Synthesis of 118-45-6.
