Ethylene dichloride and ethyldene chloride are isomeric compound . Identify the statement which is not applicable to both of them:
(b) a polyvinyl isobutyl ether having a K value of 80-150, measured with 0.5% solutions in isooctane at 20掳 C., wherein the catalysts, the ethylene/propylene/ethylidene norbornene terpolymer and/or the polyvinyl isobutyl ether and the monomer or comonomer mixture are added to the ...
Monomer and diene, along with cocatalysts are introduced into polymerization reactors. A vanadium-halide catalyst system is used and the diene of choice is ENB (ethylidene norn-bornene). Hexane serves as a hydrocarbon diluent for making a suspension of the rubber. 2. Following polymerization, the...

[Bretherick 1979. p. 160]. Ethylene in the presence of aluminum chloride may undergo a violent reaction [J. Inst. Pet. 33:254. 1947]. Ozone and ethylene react explosively [Berichte 38:3837]. Ethylene can polymerize at low pressure if catalyzed by titanium halides. (Sundaram, K. M, M...
The molecular structures of C2 (R1 = Et, R2 = H, R = Me) and C9 (R1 = iPr, R2 = H, R = iPr) were confirmed as being distorted tetrahedral at nickel by single crystal X-ray diffraction. On treatment with diethylaluminium chloride (Et2AlCl) or ethylaluminum sesquichloride (EASC),...
The solvent may be carbon tetrachloride, chloroform, ethylidene chloride, dichlorethane, trichlorethane, methylene chloride, tetrachlorethane or hexachlorethane, and chlorosulphonation may be effected with chlorine and sulphur dioxide or with sulphonyl chloride in the presence of catalysts, e.g. ...
The term EPDM is used in the sense of its ASTM designation. EPDM is a terpolymer of ethylene, propylene and a non-conjugated diene. Illustrative non-limiting examples of suitable non-conjugated dienes are 5-ethylidene-2-norbornene (ENB); 1,4-hexadiene; 5-methylene-2-norbornene (MNB), 1,6...
The diene is preferably a non-conjugated diene selected from the group consisting of 5-ethylidene-2-norbornene (ENB), 1,4-hexadiene, 1,6 octadiene, 5-methyl-1,4-hexadiene, 3,7-dimethyl-1,6-octadiene, dicyclopentadiene (DCPD), norbornadiene, 5-vinyl-2-norbornene (VNB), and combinations...
and a linear, conjugated diene in the presence of a primary, secondary or tertiary amine at about reflux temperature to form an intermediate adduct that could then be readily pyrolyzed at temperatures in excess of 600° C. to split off the desired methylidene malonate. Similarly, Ponticello (U...
