Working fluid compositions comprising carbon dioxide and a polyester

The composition has a linear or branched carbon chain with at least 6 carbon atoms and yields 4 - (CH2)m - C(=O)-O-R - groups, as well as optionally including one or more of both groups. -R and -R , where each are independent of each other and optionally for each group. R and R are each independent...

Beschreibung
Zusammenfassung:	The composition has a linear or branched carbon chain with at least 6 carbon atoms and yields 4 - (CH2)m - C(=O)-O-R - groups, as well as optionally including one or more of both groups. -R and -R , where each are independent of each other and optionally for each group. R and R are each independent from each other branched or unbranched C1 to C20 hydrocarbon-groups, which optionally 1 - 4 ether-groups (-O-) and optionally one -OH groups can be carried; R is H or one branched or unbranched C1 to C20 hydrocarbon-group and m is a whole integer from 0 to 20. An Independent claim is included for application of the rolling stock composition e.g. cold machines in power-propelled vehicle.
