Poly(imide-amide)s and poly(imide-esters)s based on silarylene units containing (l)-alanine moiety: synthesis and characterization

Silarylene-containing oligo(ether-amide)s based on bis(4-(4-amino phenoxy)phenyl)dimethylsilane. Effect of the dicarboxylic acid structure on some properties

Inherent viscosity and MALDI-TOF analyses suggest the formation of oligomeric chains with sequences A–B, (A–B)₂ and (A–B)₃. The properties and therefore the eventual applications of these materials are modulated by the flexibility and the aromatic content of the chains.

Silicon-containing oligomeric poly(imido-amides) with amino moieties. Synthesis, characterization and thermal studies

Silicon-containing oligomeric poly(imido-amides) (PIAs) were synthesized from dicarboxylic imido-acids containing a Si atom, which were obtained from dianhydrides, amino acids and p-aminobenzoic acid, were polymerized with the diamine bis(4-aminophenyl)diphenylsilane.
