Pentene has six isomers: 1-pentene (RON = 90.9 and MON = 77.1 [57]), cis-2-pentene (unknown octane number), trans-2-pentene (RON = 94 and MON = 80 [57]), 2-methyl-1-butene (RON = 100.2 and MON = 81.9 [API]), 2- methyl-2-butene (RON = 97.3 and MON = 84.7 [58]), and 3- methyl-1-butene (unknown octane number) as shown in Figure 4.

Gases detected include benzene, ethanol, ethylbenzene, heptane, hexane, isoprene, methanol, MEK, MIBK, octane, pentane, 1-pentene, toluene, xylene, butane, ethane, methane, propane, ethylene and propylene,
The comonomer can be [C.sub.2] to [C.sub.10] alkenes such as ethylene, propylene, 1butene, 1-pentene, 1-hexene, 1-heptene, 1-octene, 1-nonene, 1-decene, and 4-methyl-1-pentene.
Equistar Chemicals has obtained a patent for an adhesive composition comprised of (a) 2% to 30% weight of a modified polyolefin comprised of a polymer grafted with carboxylic acids, carboxylic acid anhydrides or derivatives thereof, the polymer being selected from a group consisting of (i) ethylene homopolymers, (ii) copolymers of ethylene with propylene, 1-butene, 4-methyl 1-pentene, 1-hexene, or 1-octene, (iii) propylene homopolymers, (iv) copolymers of propylene with ethylene or C4-C10-olefins, and (v) mixtures of (i)-(iv); (b) 0.02% to 0.3% weight of a polyalphaolefin polymer; and 65% to 98% weight of an olefin polymer base resin.
A new crystalline form has been recently reported (14-24) in the case of copolymers of iPP with high contents of 1-hexene or 1-pentene as comonomers.
The failure of the CV formulas has been attributed to numerical inconsistencies which are revisited in this work not only for CV but also for the Deiters method using the same benchmark of 48 conditions and three cubic EOS proposed by Zhi & Lee (2002), including temperatures and pressures in the ranges 87.8K [less than or equal to] T [less than or equal to] 266.3K and 3.56 x [10.sup.-7] Pa [less than or equal to] P [less than or equal to] 1.14 x [10.sup.5] Pa for propylene, 1-butene, and 1-pentene. For each PT, condition results were obtained with the PR, CCOR, and PT cubic EOS using x = Z, x = [??], and x = [??] as variables in Eq.
