Complexes of oxovanadium(lV) with N,N' -ethylene-bis-(2-aminobenzamide) [EBAB], N,N ' -propylene-bis-(2ami nobenzamide) [PBAB], N.N ' -(o-phenylene)-bis-(2-aminobenzamide) [PhBAB] , N,N' -ethylene-bis-(3-carboxypropenamide) [EBCP], N,N' -propylene-bis-(3-carboxypropenamide) [PBCP]and 1-(2'-hydroxyphenyl)-3-phenyl-I ,3-propanedione [HPPPD] have been prepared and characterized by chemical analyse...

Rigid cross-linked interpenetrated network polyvinyl chloride (PVC) foams are widely used as core materials in the composite industry. Nevertheless, no recycling methods exist today for these that currently landfilled at end of life (EoL). In this work, various amounts EoL PVC form chips were mixed with ethylene–propylene diene monomer (EPDM) rubber and carbon black (CB) 60°C 15 min. The obtain...

a series of ethylene-propylene-2-ethylidenebicyclo [2.2.1] hept.5-ene terpolymers (epdm) have been prepared using a vocl3/al2et3cl3 catalyst under various al/v ratios and diene concentrations via solution polymerization and characterized by ftir, mooney viscosity (ml1+4,125oc), and thermal gravimetery analyzing. the polymerization yield was seen to increase with augmentation of the al/v ratio a...

Abstract In this research, the effect of calcium oxide (CaO) nanocrystalline particles filled ethylene propylene diene monomer (EPDM) rubber composites is investigated, at different weight percentages (1.0, 2.0, 4.0, and 8 wt%) CaO using two methods mixing. one case conventional mixing on twin roll-mill was used, in other ultrasonic as a pre-mixing applied. are synthesized by precipitation meth...

A new product (Application 460B-00) from Agilent Technologies/WassonECE uses a 5973N GC/MSD (gas chromatograph/mass selective detector) for the determination of trace levels of impurities that are moderate-to-low carbon-content such as oxygenates, mercaptans, sulfides, arsine, and phosphine in ethylene and propylene. This work describes the performance of Application 460B-00 with respect to lin...

Rubber elongation factor (REF) and small rubber particle protein (SRPP) are two key factors for natural rubber biosynthesis. To further understand the roles of these proteins in rubber formation, six different genes for latex abundant REF or SRPP proteins, including REF138,175,258 and SRPP117,204,243, were characterized from Hevea brasiliensis Reyan (RY) 7-33-97. Sequence analysis showed that R...

Ethylene binding to seedling tissue of Vicia faba, Phaseolus vulgaris, Glycine max, and Triticum aestivum was demonstrated by determining transit time required for ethylene to move through a glass tube filled with seedling tissue. Transit time for ethylene was greater than that for methane indicating that these tissues had an affinity for ethylene. However, the following observations suggest th...
