Synthesis of Polyfunctional Polymers¹

Charge Transfer Polycondensation of 1,4-Bis(methoxycarbonylethyl)-piperazine with Hexamethylenediamine in the Presence of Nitrated Polystyrene

“…6 The amount of incorporated nitro groups was adjusted by the following reaction conditions: NPS-1 was obtained by the reaction of fuming nitric acid and PS-1 in tetrachloromethane below 40oC. NPS-2 and NPS-4 were obtained by nitration of PS-1 and PS-2 with fuming nitric acid below 0°C, respectively.…”

Electrochemical synthesis and electrochromic application of a novel polymer based on carbazole

“…Some of these synthesis methods, including copolymerization with the bonding of certain functional groups [17][18][19][20][21] modified with electro-active moieties such as, thiophene [22], fluorine [23], carbazole and pyrrole, which have been used to form electrochromic polymers with useful properties for their various applications [24][25].…”

Functionalization of Polystyrene with Cyclic Anhydrides and their Spectroscopic, Adhesive and Corrosive Characterizations

“…PS without additional functional groups has limited some properties such as thermal stability, mechanical strength, adhesion capability, corrosion resistance and photosensitivity. For this reason, the desired physical and mechanical properties of PS can be obtained by anchoring some functional groups (Kenyon and Wough, 1958;Swiger, 1975;Blanchette, 1958;Frechet et al, 1979). Thus, the undesired properties of PS can be improved using different reagents by modification reactions.…”
