Synthesis, Structure and Properties of Poly(arylene imino)s

Abstract

A series of poly(arylene imino)s (PAI) with high molecular weights and small polydispersity indices have been synthesized by the condensation polymerization of different diiodobenzenes with aromatic primary diiminos via two different methods. Their structures were characterized by means of FT-IR, 1 H NMR spectroscopy and elemental analysis. DSC and TG measurements show that the polymers possess high glass transition temperatures (T g ＞ 150 ℃) and good thermal stability with high decomposition temperatures (T D ＞400 ℃). These novel polymers also exhibit good solubility in organic solvents.

Neodymium‐Based Catalyst for the Coordination Polymerization of Butadiene: From Fundamental Research to Industrial Application

“…The values of τ of various Nd–BR are given in Figure . Generally, the processing performance became better with decreasing the value of τ . The values of τ decreased from 4.95 to 3.00 s with an increase of cis ‐1,4 content from 96.3 to 98.7%, suggesting that the increase of cis ‐1,4 content was benefit for the improvement of processability of Nd–BR.…”

Dehydroabietylamine derivatives as multifunctional agents for the treatment of Alzheimer's disease

“…Dehydroabietylamine derivatives show antimicrobial, anti-viral, anti-inammatory and free radical scavenging activities. [22][23][24][25] We have previously synthesized and evaluated the anti-oxidant activity of dehydroabietylamine derivatives in vitro. 26 In the work reported here, a series of dehydroabietylamine derivatives (Table 1; Fig.…”
