## Abstract The viscosities obtained for the copolymer blends of the previous paper were correlated with several relations derived to describe more fundamental behavior of polymerβdiluent mixtures at both infinite dilution and finite concentrations. Only the most efficient blends showed any appreci
Rates of thermal decomposition of N-acetylurea (l), N-acetylthiourea (2), N,N'-diacetylthiourea (3), and N-acetylthiobenzamide (4) have been measured over a 45 K range for each compound. The molecules were found to undergo unimolecular first-order elimination reactions for which log A = 11. 9, 11.6,
