TEXT: The n-butyl, n-amyl, n-hexyl, !I-octyll iso-
propyl, ino-amyl, and ph'~nyl eaters of 1,2-epoxy-2-propyl-pro-d-
phinic acid were prepnred by condensing the corresponding dialkyl
phosphorum acids with monachloroacetone, at 1000C, without a
cntnlyst, and removing HC1 from the resulting eaters of 1-hydroxy-
2-chloro-loo-propylphosphinic acid with alcoholic 25 - 35 % KOH.
The stabiMizing effects of these compounds on the thermal decon-
positioYx of PVC were investiRated by heating PVCO with and without
Additinns of the rhomphinates ( 0-0.5 g per.g PVC), to 173, 185,
and 1950C. The quantities meastired were the induction period until
