Ethylene polymerization using flourinated FI Zr-based catalyst
A fluorinated FI Zr-based catalyst of bis[N-(3,5-dicumylsalicylidene)-2′,6′-flouroanilinato]zirconium(IV) dichloride was prepared and used for polymerization of ethylene. It was revealed that ortho-F-substituted phenyl ring on the N electronically...

Synthesis of high molecular weight polyethylene using FI catalyst
A FI Zr-based catalyst of bis[N-(3,5-dicumylsalicylidene)-2′,6′-diisopropylanilinato]zirconium(IV) dichloride was prepared and used for polymerization of ethylene. The effects of reaction conditions on the polymerization were examined in detail...
First report of the nematodes Filenchus orientalis and Hemicriconemoides californianus on faba bean in Iran
During a survey in Iran, two known species of plant-parasitic nematodes of the families Tylenchidae
and Criconematidae were reported for the fi rst time. The morphological and morphometric
characters of Iranian populations of the two...
