APPENDIX
Claim 3. A refrigerant composition comprising a
fluorinated hydrocarbon coolant and at least one lubricant
compound of the formua:
CH O(AO) (CH CH O) H
3 m 2 2 n
wherein
AO is individually selected from the group consisting of
oxyethylene and oxypropylene,
m is a positive number in the range of 1 through 50
inclusive, provided that when m is 1, AO is oxypropylene and
when m is greater than 1, (AO)m is a polymeric difunctional
grouping selected from among members of the class consisting
of (a) polymeric groupings of oxypropylene groups and
(b)polymeric groupings each consisting of both at least one
oxyethylene group and at least one oxypropylene group,
n is a positive number in the range of 1 through 10
inclusive,
the end group at the hydrogen terminal is an oxyethylene
group, and
the total content of oxyethylene groups is in the range
of 5 through 60 weight percent based on total compound weight,
the weight ratio of said coolant to said lubricant
compound ranging from 1:99 to 99:1.
