A new class of homogeneous chromium(II1)-based catalysts of the type [Cp\*CrMeC1]2/MAO with different kinds of Cp ligands has been synthesized. The influence of the electronic nature and the sterical demand of the catalysts were explored with regard to the vinylic polymerization of norbornene. The c

In this article we will discuss the synthesis of the new copolymers of norbornene derivatives with an ester group and carbon monoxide, using Pd(CH 3 CN) 4 (BF 4 ) 2 as a catalyst and 2,2 -bipyridine as a ligand in nitromethane/methanol at 60ΠC. Elementary analysis, infrared spectra, and NMR spectra
The synthesis of a diblock copolymer of styrene and vinyl acetate (VAC), PS-b-PVAC, was performed by successive photoinduced charge-transfer polymerization (CTP) under UV irradiation. A novel amphiphilic diblock copolymer of PS-b-PVA then was obtained by the hydrolysis of the diblock copolymer PS-b-
