WebDec 12, 2024 · Abstract. The resolution and the relaxation time of poly (butyl acrylate) in latex-state 13 C-NMR spectroscopy are associated with local motions of the polymer in a dispersoid. Latexes were prepared by emulsion polymerization of butyl acrylate with ammonium persulfate. The latex-state 13 C-NMR spectra were measured at 323–353 K …

Polystyrene (PS) is a glassy, amorphous polymer with outstanding clarity, gloss, and processability. However, it suffers from inherent brittleness, limiting its use in application where deformation resistance is required. fbb f1轴Butyl rubber, sometimes just called "butyl", is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for isobutylene isoprene rubber. Polyisobutylene, also known as "PIB" or polyisobutene, (C4H8)n, is the homopolymer of isobutylene, or 2-methyl-1-propene, on which … See more Butyl rubber has excellent impermeability to gas diffusion, and the long polyisobutylene segments of its polymer chains give it good flex properties.
