wherein R and R are individually selected from the group consisting of alkyl1 2
of 1 to 12 carbon atoms and aralkyl of 7 to 15 carbon atoms or taken
together form [sic, from] a saturated heterocycle of 5 to 6 ring members
optionally having a second ring heteroatom selected from the group
consisting of sulfur, oxygen and nitrogen, R is an "-alkyl of 1 to 8 carbon
