A stereospecific synthesis of trans-l-cyanobutadiene is described. This monomer was polymerized by n-butyl lithium in toluene and in tetrahydrofuran to yield sparingly soluble products. In both solvents, the concatenation was predominatly trans-l,4with a little eis-l,4 and 3,4 content. Copolymers w

## Abstract Anionic polymerizations of 1‐adamantyl methacrylate (**1**) and 3‐methacryloyloxy‐1,1′‐biadamantane (**2**) were carried out in THF at −50 to −78 °C for 24 h. The initiator employed was either [1,1‐bis(4′‐trimethylsilylphenyl)‐3‐methylpentyl]lithium (**3**)/lithium chloride, or diphenyl
The anionic polymerization of tBMA initiated by an organolithium compound in toluene at low temperature (À78 °C and 0 °C) has been revisited. Under these experimental conditions, no `livingness' is reported, consistently with formation of an important fraction of oligomers (M n = 650).
