Help specific methods and steps about the purification of polymer diethyl ether precipitation!

Christopher Jenkins  Follow
I understand this, diethyl ether is first a dangerous thing, but it is not as dangerous.Good ventilation, effective protection, prevent static electricity, no problems such as spark, can refer to the physical properties of diethyl ether.
If your concentrate is liquid, it can be added to cold diethyl ether, and stirring and low temperature.
If it is a solid state, it can be added to diethyl ether batch and keep it stirring and low temperature.
Extraction of crystalline polymers, solid-liquid separation: filtration (filtrate), centrifugal (there is ether is very dangerous, no use).
Isothermal can be used alternative to methyl tert-butyl ether?Also must be used in ether!

There is also a problem, that is, my reactants are doing more, because time is too long, it takes two days, how is this polymeric reactant saved?
Is it possible to put a plastic wrap directly in the beaker?It can be slowly concentrated, then the precipitate is purified.
