TL;DR: In this article, a series of diamines and a tetracarboxylic dianhydride with a benzhydrol unit were obtained by one-step method polymerization, and the polymers were amorphous and had number-average molecular weight (Mn) in the range (3.0−10.2) × 104.

TL;DR: In this article, a new diimide-dicarboxylic acid, 4-(1-adamantyl)-1,3-bis(4-trimellitimidophenoxy)benzene (ADBTB), containing pendent adamantyl group was synthesized in three steps starting from adamantyl resorcinol.

TL;DR: In this article, a diamine containing noncoplanar 2,2′-dimethyl-biphenylene and flexible aryl ether units was synthesized by nucleophilic substitution with p -chloronitrobenzene, followed by catalytic reduction with hydrazine/PdC system.

TL;DR: In this paper, a new diamine, bis[4-(4-aminophenoxy)phenyl]diphenylmethane (BAPDM), bearing diphenylmethylene linkage was prepared starting from bis(4-hydroxyphenyl)diphane, which was reacted with various aromatic dicarboxylic acids to obtain a series of new polyamides with moderate to high inherent viscosities of 0.65−0.97 dL g-1.

TL;DR: In this article, the benzene rings-containing diamine, α,α-bis[3,5-dimethyl-4-(4-aminophenoxy)phenyl]-1,4-diisopropylbenzene (BDAPD), was prepared by the aromatic nucleophilic substitution of α, α-bis(4-hydroxy-3, 5-dimmethylphenyl)-1, 4-diisoopropynzene with 1-chloro-4-nitrobenzenes, and subsequent hydrogenation of the intermediate dinit
