✦ Synopsis

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 criteria for evaluating the polymerization process. The orthogonal central composition planning of the experiment was used as an approach to studying the problem; the results were processed to yield explicit mathematical equations by using a digital computer. In the region measured, the polymer yield as well as the intrinsic viscosity were found to increase with increasing temperature, initiator concentration and polymerization time.

The emulsion polymerization of tetrafluoroethylene (TFE) was carried out in a semibatch reactor using a chemical initiator (ammonium persulfate) and a fluorinated surfactant (FC-143). The effects of the reaction condition were investigated though the polymerization rate, molecular weight of polytetr

## Abstract Anionic polymerization of 2‐vinylpyridine shows significant solvent effects on the polymer stereochemistry. Polymerization with butyllithium in tetrahydrofuran (THF) yields a largely isotactic polymer, while polymerization with butyllithium in tetramethyl‐ethylenediamine (TMEDA) results
