Abstract

The telechelics 1 from methyl methacrylate and 1,1,2,2‐tetraphenyl‐1,2‐diphenoxyethane, can be separated by adsorption chromatography. The structure of the dimers and trimers was identified by ^1^H NMR‐spectroscopy. The free radical oligomerization is a process in which the syndiotactic structure is favoured above the isotactic one.

## Abstract The polymerisation of methyl methacrylate (MMA) by 1,1,2,2‐tetraphenyl‐1,2‐diphenoxyethane is characterised by three steps: during the initial period oligomers from MMA and initiator radicals are formed by primary radical termination. These oligomers produce free macroradicals and initi
