For PLA chloroform or methylene chloride would be useful.

Rega Permana

Chitosan will dissolve in weak acid. For PLA it can disolve in chloroform, acetone or dimethyl sulfoxide (DMSO). You have to dissolve each in their suitable solvent first and then blend them. This paper showed how the exact procedure for blending them, maybe you can follow them https://pubs.acs.org/doi/abs/10.1021/bm0600825

But if you need highly volatile solvent chloroform would be best I think.
