Synthesis of a Methacrylate-Type Monomer Containing C60 Unit and Copolymerization with t-Butyl Methacrylate.

Kinetics of the Radical Copolymerization of 2,2,2- Trifluoroethyl methacrylate with tert-Butyl - trifluoromethacrylate

The radical copolymerization of two different methacrylate monomers, 2,2,2trifluoroethyl methacrylate (TFEMA) and tert-butyl -trifluoromethacrylate (TBTFMA) in solution was investigated. The resulting statistic poly(TFEMA-co-TBTFMA) copolymers were characterized by NMR spectroscopy to assess their compositions. The kinetics of copolymerization enabled one to determine the reactivity ratios of ...

Solubility and diffusivity of solvents and nonsolvents in poly(methyl methacrylate co butyl methacrylate)

In this study, thermodynamic properties, namely retention volume, infinitely dilute weight fraction activity coefficient, Flory–Huggins interaction parameter, solubility parameter of the polymer, partition coefficient and diffusion coefficients of the various solvents in poly(methyl methacrylate co butyl methacrylate) (PMMA co BMA) at infinite dilution of the solvent have been determined by inv...

Statistical determination of chemical composition and monomer sequence distribution of poly(methyl methacrylate-co-tert-butyl methacrylate)s by multivariate analysis of 13C NMR spectra

To evaluate chemical compositions and heterogeneity of comonomer sequences in methyl methacrylate (MMA)-tert-butyl methacrylate (TBMA) copolymers, multivariate analysis was applied to the 13C nuclear magnetic resonance (NMR) spectra of the carbonyl, backbone quaternary and a-methyl carbons of the copolymers. A better linear relationship was found between the first principal component score and ...

Papain-Catalyzed Synthesis of Polyglutamate Containing a Nylon Monomer Unit

Peptides have the potential to serve as an alternative for petroleum-based polymers to support a sustainable society. However, they lack thermoplasticity, owing to their strong intermolecular interactions. In contrast, nylon is famous for its thermoplasticity and chemical resistance. Here, we synthesized peptides containing a nylon unit to modify their thermal properties by using papain-catalyz...

Self-structuring in amphiphilic networks prepared by single conventional radical copolymerization of n- butyl methacrylate and vinylpyrrolidone
