## Aluminum tetraphenylporphyrin was anchored onto polystyrene cross-linked with divinylbenzene ((~-R-OTPPAI-X). (~-R-OTPPAI-X behaves as an initiator for the polymerization of propylene oxide (PO) to give poly(propylene oxide) (polyPO) with narrow molecular weight distribution in the presence of al
The kinetics of ethylene oxide polymerization in THF, with Na, K and Cs-naphthalene complexes as initiators, have been studied in detail. Polymerization is first order with respect to monomer without chain termination or transfer. The complicated dependence of the polymerization rate on active cent
