Conventional and atom transfer radical copolymerization of phenoxycarbonylmethyl methacrylate-styrene and thermal behavior of their copolymers

open access: yeseXPRESS Polymer Letters, 2007
The atom transfer radical polymerization (ATRP) of phenoxycarbonylmethyl methacrylate (PCMMA) with styrene (St) were performed in bulk at 110°C in the presence of ethyl 2-bromoacetate, cuprous(I)bromide (CuBr), and N,N,N’,N”,N”-pentamethyldiethyltriamine.

Carbazole based electrochromic polymers with benzoazole units: Effect of heteroatom variation on electrochromic performance

open access: yeseXPRESS Polymer Letters, 2016
A series of carbazole-based polymers were synthesized via Suzuki polymerization between N-(2-ethylhexyl)carbazole-3,6-bis(ethyleneboronate) (Cbz) and dibromobenzazole unit.

Polycondensation of pyrrole and benzaldehyde catalyzed by Maghnite–H+

open access: yeseXPRESS Polymer Letters, 2007
Rapid synthesis of poly[(pyrrole-2,5-diyl)-co-(benzylidene)] was achieved under microwave irradiation via the condensation of pyrrole and benzaldehyde in 1,2-dichloroethane using acid exchanged montmorillonite clay called Maghnite–H+ (Mag–H+) as an ...

Liquid crystalline polymers IX Main chain thermotropic poly (azomethine – ether)s containing thiazole moiety linked with polymethylene spacers

open access: yeseXPRESS Polymer Letters, 2007
A new homologous series of thermally stable thermotropic liquid crystalline poly(azomethine-ether)s based on thiazole moiety were synthesized by solution polycondensation of 4,4`-diformyl-α,ω-diphenoxyalkanes, I–IV or 4,4`-diformyl-2,2 ...

Preparation of aromatic polyamidines and their transformation in polybenzimidazoles

open access: yeseXPRESS Polymer Letters, 2014
Polymers with amidine groups –NH–C(=NH)– in main chain were synthesized by two different approaches. The first strategy consists in polyaddition of dinitriles and diamines in acidic ionic liquids (ILs) which act as catalyst and solvent, while the second ...
