The reactivity ratios for the copolymerization of methyl and ethyl methacrylates were calculated by the method of Kelen and Tudos. The triad sequence distributions were then determined by means of a computer program due to Harwood. The calculated distributions agree well with those found by 13C-IH-N
Unusual assignments have been observed for the 1H-NMR of alkoxy groups in syndiotactic methyl methacrylate-methacrylic acid (MMA-MAA) copolymers and methyl methacrylate-diphenylmethyl methacrylate (MMA-DPMMA) copolymers. Thereby, the alkoxy groups --OCH3 and --OCH < show a degenerate pentad assignme
Dilute solutions of methyl methacrylate-methacrylic acid copolymers (with low content o f methacrylic acid) in ethylene dichloride exhibit the effect of antithixotropy which manifests itself in the time dependence on the shear stress (in rotatory viscometers) and in the upturn on the shear stress de
