“…On the other hand, N ‐substituted maleimides have become interesting monomers because of the superiority of their polymers or copolymers in thermal stability 18–21. To get heat‐resistant transparent hyperbranched polymers, the copolymerization of 4‐(chloromethyl)styrene (CMS) and N ‐cyclohexylmaleimide (NCMI) using ATRP with CMS as inimer was studied in this work.…”

The hyperbranched copolymers were obtained by the atom transfer radical copolymerization of p‐(chloromethyl)styrene (CMS) with N‐cyclohexylmaleimide (NCMI) catalyzed by CuCl/2,2′‐bipyridine (bpy) in cyclohexanone (C6H10O) or anisole (PhOCH3) with CMS as the inimer. The influences of several factors, such as temperature, solvent, the concentration of CuCl and bpy, and monomer ratio, on the copolymerization were subsequently investigated. The apparent enthalpy of activation for the overall copolymerization was measured to be 37.2 kJ/mol. The fractional orders obtained in the copolymerization were approximately 0.843 and 0.447 for [CuCl]0 and [bpy]0, respectively. The monomer reactivity ratios were evaluated to be rNCMI = 0.107 and rCMS = 0.136. The glass transition temperature of the resultant hyperbranched copolymer increases with increasing fNCMI, which indicates that the heat resistance of the copolymer has been improved by increasing NCMI. The prepared hyperbranched CMS/NCMI copolymers were used as macroinitiators for the solution polymerization of styrene to yield star‐shaped poly(CMS‐co‐NCMI)/polystyrene block copolymers by atom transfer radical polymerization. © 2000 John Wiley & Sons, Inc.

“…All polymers had a lower MBr fraction than perfectly alternating copolymers, which would have had an MBr fraction of 0.5. However, the copolymerization of MI and acrylates has a tendency toward alteration that has already been observed kinetically for the radically initiated copolymerization of such monomers 40–42…”

The synthesis of novel copolymers consisting of a side-group liquid-crystalline backbone and poly (methyl methacrylate) grafts were realized by the use of atom transfer radical polymerization (ATRP). In the first stage, the bromine-functional copolymers 6-(4-cyanobiphenyl-4 0 -oxy)hexyl acrylate and (2,5-dioxo-2,5-dihydro-1H-pyrrole-1-yl)methyl 2-bromopropanoate were synthesized by free-radical polymerization. These copolymers were used as initiators in the ATRP of methyl methacrylate to yield graft copolymers. Both the macroinitiator and graft copolymers were characterized by 1 H-NMR, gel permeation chromatography, differential scanning calorimetry, and thermogravimetric analysis. The ATRP graft copolymerization was supported by an increase in the molecular weight of the graft copolymers compared to that of the macroinitiator and also by their monomodal molecular weight distribution.

“…Meanwhile, N ‐substituted maleimides have become interesting monomers because of the superior thermal stability of their polymers or copolymers 19. 21–26 In order to obtain heat‐resistant transparent copolymers with well‐defined architecture, controlled molecular weight and narrow polydispersity, the copolymerization of MMA and NCMI using ATRP was studied and is reported below.…”
