Partially fluorinated maleimide copolymers for Langmuir films of improved stability, 1. Synthesis, copolymerisation behaviour and bulk properties

Abstract

Various new partially fluorinated polymers on the basis of substituted N-phenylmaleimides are prepared by radical copolymerisation. Nearly alternating copolymers are produced with vinyl ethers and styrene derivatives. The copolymers show high stability against thermal degradation in comparison to conventional vinyl and vinylidene polymers, and high glass transition temperatures. Highest thermal stability is found for copolymers in which the classical hydrophilic and hydrophobic fragments are reduced to a minimum.

Development of Photosensitive Vinyl Polymers with Imide Group Based on Reaction Development Patterning

“…Copolymerization of maleimides with electrondonating monomers is known to give copolymers with high molecular weight [18,19]. In this study, we adjusted molecular weight of PMS, PMnBE and MMnBE by using dodecanethiol as a chain-transfer agent.…”

Tailored Polymer Microstructures Prepared by Atom Transfer Radical Copolymerization of Styrene and N‐substituted Maleimides

“…[39] Afterwards, examples of radical copolymerization of styrene with N-phenyl maleimide, [40] N-benzyl maleimide, [41] N-cyclohexyl maleimide, [41] N-allyl maleimide, [42] N-(2-chlorophenyl) maleimide, [43] N-(4-carboxyphenyl) maleimide, [44] N-hydroxymethyl maleimide, [45] N-hexyl maleimide, [41] N-(4-hydroxyphenyl) maleimide, [46] N-(4-trifluoromethylphenyl) maleimide, [47] N-[3,5-bis(trifluoromethyl)phenyl] maleimide, [47] N-pentafluorophenyl maleimide, [47] and N-maleoyl L-amino acids [48] have been reported. [49] All these radical copolymerizations share a strong tendency toward AB alternation.…”

Multinuclear NMR studies and ab initio structure calculations of hindered phencyclone diels‐alder adducts from symmetrical cyclic dienophiles: Cyclohexene, vinylene carbonate, vinylene trithiocarbonate and two N‐aryl maleimides

“…Published proton and carbon-13 NMR data for 2e have appeared, for d 6 -DMSO solutions [14], so our present data in CDCl 3 are complementary. Laschewsky and co-workers had reported the 19 F NMR absorption for a CDCl 3 solution at -60.55 ppm, somewhat different from our observed value of -63.42 ppm, but fluorine chemical shifts can be temperature-and concentration-dependent.…”

“…Prepared by standard methods [13,14], by cyclodehydration of the precursor N- [3,5-bis(trifluoromethyl)phenyl]maleamic acid in acetic anhydride with anhydrous sodium acetate at 90-100°for ca. 1.5 hr.…”
