Title

ETHYLENE/PROPYLENE COPOLYMERIZATION USING CP2ZRCL2/MAO CATALYST: EFFECTS OF COPOLYMERIZATION CONDITIONS ON VISCOSITY AVERAGE MOLECULAR WEIGHT

Pages

  15-21

Abstract

 Copolymerization of ethylene with propylene is carried out semi-continuously in toluene at atmospheric pressure and with various propylene/ethylene molar ratios. The polymerization temperature and cocatalyst/catalyst molar ratio were also varied in a wide range. Cp2ZrCl2/MAO System was used as catalyst. The VISCOSITY AVERAGE MOLECULAR WEIGHTs of copolymers obtained were determined by measuring the intrinsic viscosity [ h] and application of the Mark-Houwink equation. The values of molecular weights were found to be dependent on operating conditions except on polymerization time in the range 5-30 min. increasing the polymerization temperature, propylene/ethylene and cocatalyst/catalyst molar ratios caused a continuous decrease in molecular weight. An important reason for this effect was shown to be accelerated CHAIN TRANSFER REACTIONs.
