A comprehensive I3C-NMR method for the analysis of composition in the most common commercial polyethylene copolymers has been established. The method covers ethene copolymers with propene, butene-1, hexene-1, octene-1, and 4-methyl pentene-1 in the composition range of 1-10 mol %. The chemical shift

13 C NMR spectra of copolymers of methyl methacrylate and tert-butyl methacrylate with various chemical compositions, the homopolymers of the two methacrylates, and blends of the homopolymers with various blend ratios were subjected to principal component analysis. The first and second principal com
Acrylic acid-vinyl acetate copolymers were prepared in bulk using benzoyl peroxide as initiator. Copolymer compositions were determined by volumetric titration; monomer reactivity ratios were determined by the method of Kelen-Tiidrs. Terminal and penultimate reactivity ratios have been calculated u
