Dear GMX user,
Explicated model of Poly (vinyl methyl ether) was built with ether parameters
in OPLS Force Field. The density and radius of gyration of PVME melts fit
experimental value well. And then it was solvated in Tip5p.
In experiment, PVME should solvate in water well in ~300k. However, it totally
collapsed in my model. I have changed temperature and electricity but no help.
How can I find a acceptable model? Any suggestion will be appreciated !!!!!!
I feel increasing the polarity of PVME maybe helpful. Is it right?
Thanks in advance.
