If polylactic acid has already been dissolved in the organic solvent, when the temperature is risen above its glass transition temperature, will this affect the behavior or properties of this polymer in the solvent? Will the polymer chain more flexible?

Thanks.

Glass transition temp refers to behavior in the solid phase. While there are many interesting relationships between temp and polymer behavior in solution, Tg isn't really solidly connected to them.
