The main kinetic laws governing 4-methylpentene-I (MP) polymerization and copolymerization with propylene (P) on the catalytic system TiCI 3 + (C2Hs)gAIC1 between 30 and 70 Β° were studied. The MP homopolymerization is kinetically first-order in monomer and TiCl> The effective activation energy is 8'
## Abstract The polymerization of norbornene (NBE) was investigated in the presence of two novel pyrazolylimine nickel complexes [2β(C~3~HN~2~Me~2~β3,5){C(Ph)ο£Ύ[4βR~2~C~6~H~2~(R~1~)~2~β2,6]}NiBr~2~ (complex 1, R~1~ = ^i^Pr and R~2~ = H; complex 2, R~1~ = H and R~2~ = NO~2~)] activated by methylalumi
