摘要

Abstract

The polymerization of e-caprolactone (CL) or propylene oxide (PO) with tetra-phenylporphyrin (TPP)-diethylaluminium chloride (et2AlCl) as catalyst in toluene gives the polymer with narrow molecular weight distribution and is living polymerization in nature.From the living polymerization of CL or PO the block compolymers of PCL-PPO or PPO-PCL were prepared

The M

and Mw/Mn of homo-or copolymers were determined by GPC and showed that the M

increased linearly with the increase of conversion and the value of Mw/Mn was 1.19-1.25

indicating the narrow distributi-on of the molecular weights. The ratio of CL/PO (mole/mole) in the block copoly-mers were estimated by GPC or NMR spectroscopy.
