A study was made of the effect of Et~ N and 2, as donor additives on the catalysts (a) MgC12/TiC14/AIEt 3 , (b) f-TiC13/AIEt 3 and (c) 6-TIC13/ZnEt 2 for propylene polymerization. The productivity trends show a maximum, at low base concentration, in the presence of the A1Et 3 based catalysts (a) and

A mathematical procedure for the investigation of the lattice disorder by stacking faults in polycrystalline solids has been used in studying samples of MgCI 2 activated by ball milling for various times in the presence of TIC14. These samples have been investigated by X-ray diffraction and by measu
MgCl, supports were prepared by the recrystallization method with variation of agitation speed and MgCl, concentration of the MgC1,-methanol-decane mixture. It was found that the particle size of MgCl, and MgCl,/TiCl, could be controlled by changing the MgCl, concentration in a methanol droplet or b
