when taken together are C1-C10 alkylene;
<IMG> ; <IMG> ;
<IMG> ; <IMG> wherein R"" is C1-C10
alkoxy; <IMG> ; <IMG> ; <IMG>
and <IMG> ,
and R is selected from the groups represented by the formula
(1) -OR1;
(2) <IMG> ; or
(3) <IMG>
wherein
- R1 is selected from the group consisting of C1-C10 alkyl,

(claim 94 cont'd)
- R2 and R3 are selected from the group consisting of hydrogen,
C1-C10 alkyl, C7-C15 aralkyl, and C1-C10 alkyl substituted with
a group selected from C1-C10 alkoxy, C2-C10 alkoxycarbonyl and
carboxy; and
- Z is a divalent group which consists of two or more groups
selected from methylene -CH2- and monosubstituted methylene
<IMG> (wherein R4 is selected from the
group consisting of C1-C10 alkyl and C1-C10 alkoxy), and zero or,
one or more than one group selected from oxy-O-, thio-S-,
alkyl substituted imino
<IMG> (wherein R5 is C1-C10 alkyl) and
acyl substituted imino
<IMG> (wherein R6 is C1-C10 alkyl),
which are combined in an arbitrary order, the number of the
combined groups being up to 20; whenever prepared by the process
of claim 93 or an obvious chemical equivalent thereof.
