The effects of temperature and initiator and activator concentrations on the anionic polymerization of 2-pyrrolidone were studied. Potassium tert. butanolate and ),-butyrolactone served as initiator and activator respectively. The polymer yield and intrinsic viscosity of the polymer were employed as
## Abstract The kinetics of the initiation of isoprene polymerization in heptane with the hydrocarbonโsoluble alkylsodium compound 2โethylhexylsodium was studied. Initiation rates were estimated from the induction period and by measuring UV spectra of polyisoprenylโsodium (ฮป~max~ = 304 nm) during t
The ion-pair propagation rates for isoprene have been determined in tetrahydrofuran with counter-ions lithium and sodium. Because of the instability of the carbonions of diene monomers in this solvent, a parallel spectroscopic study was carried out to check for the occurrence of side-reactions. With
