Polyamides, or nylons, are an attractive class of engineering polymers due to their excellent strength and stiffness, low friction and chemical and wear resistance.This study is focused on the role of ethylene propylene ruber on the fracture...

replaced with Lecithin and Propylene glycol). At the end of 3 and 6 weeks of the trail, carcass characteristics were measured. Chromic oxide was used for nutrient digestibility measurement. Diet with 2.5% tallow + 2.5% ERP10 + 4% replaced Lecithin with fat...

,10-diylidene)bis(2,6diisopropylaniline)]nickel(II) n2 was determined by C NMR technique. Sequences distribution of ethylene (E), propylene (P), EP, inverted propylene and uninterrupted methylene and also methylene number-average sequence lengths...

sequences with melting temperatures higher than that of 100% crystalline polyethylene
indicating ethylene/propylene copolymer analogues. For catalysts C3
and C4, more vinyl end groups were a result of the long distance between the
Ni centers. Kinetic profiles...

Kinetic studies of different MgCl2-supported Ziegler-Natta (ZN) catalysts are carried out during propylene polymerization in slurry phase. Three main procedures for preparing various MgCl2-supported ZN catalysts including grinding, solution...

Various elastomeric polypropylenes (PPs) are synthe-

sized through homogeneous propylene polymerization with met-

allocene catalyst (2-PhInd)2ZrCl2 in the presence of different

cocatalyst mixtures: triethylaluminum (TEA...
