Primero deberías de hacer pruebas de solvencia de tu polímero con distintos disolventes, ya que no todos los sólidos son solubles en todos los disolventes, y decidir según solubilidad. Vas a necesitar disolventes orgánicos si no es soluble en agua, y muchos de ellos son inflamables/tóxicos/carcinogénicos, etc.

I doubt that there would be any generic solvent to dissolve any polymer. If you are looking for a solvent of intermediate polarity like acetone and want to avoid chlorinated solvents a possible alternative would be methyl tetrahydrofurane.

An alternative is butanone (button-2-one) - this is similar to acetone, but has a much higher boiling point. It is often used for alkylations etc. It has a bp of 79-80 compared to 56 degrees of acetone.

I hope this helps.

Kindly check; Polarity Index

Burdick & Jackson solvents are arranged in order of increasing polarity index, a relative measure of the degree of interaction of the solvent with various polar test solutes.

Apart from your desired solvent qualities ( non-flammability and low boiling point), the choice will be totally dependent on the family/ class which the polymer  belongs. Based on the principal that 'like dissolves like, the attached document will provide you with good ideas on which solvent to use when a particular repeating unit of the polymer is involved.

The selection of alternate solvent solely depends on the nature of your compound. From green chemistry viewpoint I would recommend ethyl acetate. 

I already tried Ethyl Acetate and nothing happened. I guess Butanone could be a good choice for the reasons you mention. Thank you all for your contributions!

N-methyl-2-pyrrolidone (NMP) can be used. It is a polar aprotic solvent and dissolves many polymers. It has high boiling point ( >200 degree centigrade)  It is soluble in water and easy to dispose which is a great advantage during work up of reactions.

I also recommend ethyl acetate

You can try ethyl methyl ketone.

Methyl isobutyl ketone

I recommend ethyl acetate or try CH3CN

I recommend ethyl methyl ketone

Typical organic solvents are usually flammable with exception of chloroform and other polyhalogenated hydrocarbons. Maybe halotan CHBrClCF3 would be suitable?

Thank you all for your contributions. The first assay shows that apparently MEK is a suitable option. It has dissolved main part of the polymer and it is less volatile than acetone, which is a good point. I am considering a mixture of IPA and 1,4-dioxane, since I have read it can be a good option too. I'll come back with more test results!

DMSO

Dear Xavier Sanz

Did you try a mixture of  1,4-dioxane and DMF?

As far as I know, methyl acetate is occasionally used as a solvent that is quite similar to acetone...

Yes, as Grzegorz Rarata mentioned methyl acetate is occasionally used as a solvent that is quite similar to acetone.

 ENG-TIPS.com  suggested...Methylene chloride ...but for health issues....flammability values are known to be very low or close to zero

Hi, I have visnagin CAS number 82.57.5 is soluble in acetone, but I need a more biological solvent for my experiments. Anyone may help me please?

Thank you.

Gustavo

Did you try Diphenyl ether?

Hi, I found an old patent (1954) they used saccharine!! and that work better than acetone.

Thank you.

Gustavo.

Dear Gustavo Sosa

I did not used saccharine before as a solvent, however I used a Lemon juice and it worked well.

saccharine !!!!!!!!!!!!! are you joking???

NMP (N-Methylpyrrolidine) can be used. It is a polar , water soluble solvent with high boiling point (about 202-204 degree centigrade). It dissolves many polymers easily. Of course like other organic compounds it is combustible but not highly inflammable like ether, acetone, ethyl acetate or benzene. It's self ignition temperature is about 250 degree. I think one can use it as solvent for polymers.
