Summary

Radical copolymerization of methyl methacrylate (MMA,M 1) with 2-naphthyl methacrylate (2NM,M 2) is characterized by the reactivity ratios:

$$\begin{gathered} r_1 = 0.33 \pm 0.08 \hfill \\ r_2 = 1.93 \pm 0.16. \hfill \\ \end{gathered}$$

Analysing the α-CH3 signal in the1H-NMR spectra, the coisotactic alternating addition probability is found to be σ = 0.25.

Zusammenfassung

Die radikalische Kopolymerization des Methylmethacrylats (MMA,M 1) mit 2-Naphthylmethacrylaten (2NM,M 2) kennzeichnet sich durch die folgenden Reaktivitätsverhältnisse:

$$\begin{gathered} r_1 = 0.33 \pm 0.08 \hfill \\ r_2 = 1.93 \pm 0.16. \hfill \\ \end{gathered}$$

Die Analyse des α-CH3 signals in1H-NMR Spektren ergab eine koisotaktische alternierende Additionsprobabilität von σ = 0.25.
