Ethylene Market Share, Size, Trends, Industry Analysis Report by Feedstock (Naphtha, Ethane, Propane, Butane and Others), by Application (Polyethylene, Ethylene Oxide, Ethyl Benzene, Ethylene Dichloride, and Ot
The main object of this report is to review and summarize the current state of the scientific literature relating to physico-chemical ageing of ethylene–norbornene copolymers (ENCs). These processes occur through different means such as photodegradation under the effect of ultraviolet radiation, tempera...
(CH2Ph)2, and {1,2-bis(2,6-diisopropylphenylamide)-tetramethyldisilane}titanium dichloride, {(Me2SiN[2,6-iPr2Ph])2} TiCl2, [0009] The bis-amido compounds of formula (I) can be prepared according to procedures known in the state of the 10 art, and more specifically as described ...
In this work, a phosphorous-containing flame retardant, phenylphosphonate-based compound (EHPP), is synthesized by alcoholysis and hydrazinolysis of phenylphosphonic dichloride, which is subsequently introduced to ethylene-vinyl-acetate (EVA) copolymer to improve its flame retardant performance. The result...
Afterward, 0.1 mmol of, in terms of titanium, the titanium catalytic component prepared in the above-mentioned (1) and 0.67 micromol of ethylenebisindenylzirconium dichloride were promptly added, thereby initiating the copolymerization of ethylene and 1-octene. While ethylene was fed, reaction was...
Examples of solvents used for the solvent polymerization method or the slurry polymerization are aliphatic hydrocarbons such as butane, pentane, hexane, heptane and octane; aromatic hydrocarbons such as benzene and toluene; and halogenated hydrocarbons such as methylene dichloride. ...
and dibutyl aluminum chloride; alkylaluminum sesquihalides such as ethylaluminum sesquichloride; alkylaluminum dihalides such as ethylaluminum dichloride, ethylaluminum difluoride, and butylaluminum dichloride; and dialkylaluminum alkoxides such as diethylaluminum ethoxide, diethylaluminum butoxide, and diethyl...
Catalyst (D1) is bis(dimethyldisiloxane)(indene-1-yl)zirconium dichloride available from Sigma-Aldrich:Shuttling Agents The shuttling agents employed include diethylzinc, di(i-butyl)zinc, di(n-hexyl)zinc, triethylaluminum, trioctylaluminum, triethylgallium, i-butylaluminum bis(dimethyl(t-butyl)...
(TIBA), tri-n-octylaluminium, methylaluminium dichloride, ethylaluminium dichloride, dimethylaluminium chloride, diethylaluminium chloride, ethylaluminiumsesquichloride, methylaluminiumsesquichloride, and alumoxanes (also referred to as aluminoxanes). Alumoxanes are well known in the art as typically ...
