Quantitative structure-property relationships (QSPR) between the melting points of oligomethylenes and quantum chemical data calculated by the semiempirical method CNDO/ 2 were investigated. A linear relationship between the average net charges of hydrogen and carbon atoms in the molecules and the m

The melt spinning of two thermotropic cellulose derivatives-trimethyl silyl cellulose and phenyl acetoxy cellulose-is described in this article. Removal of the substituents was facile, rapid, and essentially complete. Both the melt-spun and regenerated fibers had banded textures typical of fibers sp
The generally higher melting-point of a para-disubstituted benzene relative to the corresponding metaisomer has been ascribed to the fact that, being more symmetrical, it can pack more tightly. Exceptionally, it was observed that whereas m-anisylpinacolone melts at 58.0 ยฐC, the para-isomer melts low
