Polymerization kinetics analysis of a thermostable, sequence-controllable polyamide polymer

The copolymer of N-phenylmaleimide (N-PMI) and furan was combined by thermally reversible Diels-Alder reactions to prepare functionalized monomer N-phenylmaimide (F-NPMI). By setting a reasonable temperature floating instruction to achieve reversibly removing protection of N-PMI imide carbon double bonds (C=C) furan groups, control of supply/receptor comonomer pair (NPMI/St) Atomic transfer radical polymerization(ATRP) of deviation molar ratio, a functionalized heat-resistant molecule-sequence control N-phenylmaimide-maleic anhydride binary copolymer (PNMS) is prepared. FT-IR and 1 H and 13 C NMR analyses showed the successful preparation of the F-NPMI and sequence-controlled PNMS. Tg, DSC analysis further proves that sequence-controllable PNMS have good thermal stability (T d =452.5°C, T g =209.2°C). In addition, this paper draws that can reflect the reaction kinetics curve of polymerization process control and can reflect the N-PMI monomer into PNMS function relation curve of the speed of the polymer chain, effectively proves that PNMS sequence structure is effectively controlled in the polymerization process.
