I think the viscosity of solution is correlated closely with contcting force between dissolved polymers. it is considerd that solvent type affects the force.

1: I ' m sorry. I don't know PLC.

2: It is also considered that the solution viscosity would be concerned with  the extent of 

entanglement between dissolved polymers,

which is  depending on solvent types. 

Dear Rahul,

I hope the following paper could be useful. it presents data on PCL solutions in 7 solvents.

Paola

Thank you. I will certainly look into it.
