✦ Synopsis

The effect of polymerization temperature on radical reactivity ratios in the copolymerization of styrene and methyl methacrylate, and on the microstructure of the resulting copolymers, has been investigated by the application of high resolution nuclear magnetic resonance techniques. Analysis of the NMR spectra was facilitated by the use of partiallydeuteratedcopolymers. Copolymerizations are described which were conducted at --30 Β° and at --60 Β° using as free radical initiator a novel cobalt complex, containing molecular nitrogen as a ligand, in conjunction with an alkyl halide.

## Abstract The mechanism of the Gilch polymerization leading to poly(__p__‐phenylene vinylenes) is still a matter of controversial discussion. Similar to some other research groups, we strongly favor a basically radical process. Moreover, we believe it is initiated by spontaneously formed diradica

Abstraet--A report is given of effects of tetramethyithiuram monosulphide (TMTM) upon the polymerization of styrene at 80 Β°; it can act as both an initiator and a retarder and there is great sensitivity to light. Experiments with ~4C-TMTM show that transfer to initiator is important. Attempts were m
