TL;DR: In this paper, a review of studies of the α, β-crystals in sPS was investigated by studying miscible blends of sPS with atactic polystyrene, and provides comprehensive discussions on the thermal behavior, crystal structures, thermodynamics, kinetics, and stability of these two major crystal packings (α vs. β) in SPS upon melt crystallization in comparison with cold crystallization.

TL;DR: The diamine II was derived by a nucleophilic substitution of 9,9-bis(4-hydroxyphenyl)fluorene with p-chloronitrobenzene in the presence of K2CO3 and then hydro-reduced as mentioned in this paper.

TL;DR: In this article, a novel fluorinated bis(ether amine) monomer, 2,3-bis(4-amino-2-trifluoromethylphenoxy)naphthalene, was prepared through the nucleophilic aromatic substitution reaction of 2-chloro-5-nitrobenzotrifluorside and 2-3-dihydroxynaphthalenes in the presence of potassium carbonate, followed by catalytic reduction with hydrazine and Pd/C.

TL;DR: In this paper, 3,3-Bis[4-(4-aminophenoxy)phenyl]phthalide (II) was used as a monomer with various aromatic dicarboxylic acids and dianhydrides to synthesize polyamides and polyimides, respectively.

TL;DR: A novel fluorinated diamine monomer, 9,9-bis[4-amino-2-trifluoromethylphenoxy)phenyl]fluorene (II) was prepared via the nucleophilic substitution reaction of 2-chloro-5-nitrobenzotrifluorside with 9, 9-bis(4-hydroxyphenyl)fluorenes in the presence of potassium carbonate, followed by catalytic reduction with hydrazine and Pd/C as discussed by the authors.
