A trivial case of macromolecular isomorphism involves the mixing of species differing only in an isotope, for example, as isotactic polypropylene and isotactic polydeuteropropylene (Natta et ai, 1958). More interesting examples can be realized by melting together such polymers as poly(vinyl fluoride) and poly(vinylidene fluoride) (Natta et a/., 1971) or poly(isopropyl vinyl ether) and poly(sec-butyl vinyl ether) (Allegra and Bassi, 1969) that form isomorphic pairs at all relative compositions.

Additional examples of isomorphism include poly(isopropyl vinyl ether)/poly(sec-butyl vinyl ether) (PiPVE/PsBVE) and isotactic poly(4-methyl pentene)/isotactic poly(4-methyl hexene) (iP4MP/iP4mH) [314]. PiPVE/PsBVE blends were cocrystalline over the entire composition range, whereas iP4MP/iP4mH blends were isomorphic only in the range of 0-25 wt% of either constituent. For these blends, the chain axes and chain symmetries are identical, thus isomorphic behavior is possible. HDPE/LLDPE blends have been noted to be cocrystalline within limits of the comonomer incorporation in LLDPE. A comprehensive study of this...

The first reaction was found by Levy and Szwarc to be predominant when methyl radicals attacked isooctane. The second reaction is predominant, however, for aromatic hydrocarbons. The free radicals formed in the above two reactions will react with each other, with other free radicals, or with impurities. The affinity of the methyl radical to attack an aromatic increases in the following order benzene, diphenyl ether, pyridine, diphenyl, benzophenone, naphthalene, quinoline, phenanthrene, pyrene, and anthracene. The ability of free alkyl radicals to interact with isopropylbenzene and cyclohexene decreases in the following order methyl, ethyl, propyl, butyl, isopropyl, sec-butyl, and tertiary butyl.

Precision—The precision of these test methods was determined by statistic analysis of interlaboratory test results. Twelve laboratories analyzed in duplicate eight different samples, providing a total of thirteen data sets. One laboratory us two different test methods. The breakdown on data sets by test method is Test Method A, three Test Method B, two Test Method C, three Test Me od D, five. The statistical analysis was performed on the set of 13 data sets because the reductive pyrolysis technique is common to all four test methods. Separate statistics were not determined for individual test methods. The sample set included anhydrous methanol and gasoline stocks that were spiked with one or more of the following isobutanol, n-butanol, sec-butanol, tfrt-butanol, di-isopropyl ether, ethanol, ethyl ten-butyl ether, methanol, methyl rm-butyl ether, n-propanol, isopropanol, tert-amyl methyl ether.
