Polymers which are miscible in oil Can someone suggest me a list of polymers or some paper where I may find polymers that are soluble in oils like silicon oil, mustard oil, coconut oil, bean oil or petroleum ether, etc.?
Plastics Design Library series include tabulated parameters for the variety of polymers.
One of such parameters is a PDL number rating from 0 to 9:

0: solvent dissolved disintegrated
1: decomposition
2: severe distortion; oxidizer and plasticizer deteriorated
…
9: highest resistance, no change

In the table below I assembled data on thermoplastics chemically unstable towards various oils with PDL numbers below 3:
