What is an alternate way to recover a polymer product from DMSO or DMF other than evaporation?

Due to the high b.p of DMSO and DMF (189 and 153 degree Celsius), it is difficult to recover my polymer from the solution. I believe extraction in a triple system (such as DCM, DMSO and water)...

This isn't a physiological test, however many studies that aim to quantify impulsivity (including physiological studies; see Kaladjian et al., 2011. Psychological Medicine, 41, 291-299) will use the Barratt Impulsiveness Scale (BIS-11; Patton, Stanford & Barratt, 1995. Journal of Clinical Psychology, 51, 768-74) or UPPS Impulsive Behaviour Scale (Whiteside & Lynam, 2001. The five factor model and impulsivity: using a structural model of personality to understand impulsivity. Personality and. Individual Differences, 30, 669–689).

Otherwise, while not standardized, performance on the Go-NoGo task (as well as psychophysiological measures such as the P300 event-related potential) has been used as a proxy for impulsivity (see Dong et al., 2010. Neuroscience Letters, 485, 138-142).

Other non-physiological tests are Continuous Performance Tasks (CPT), namely: Integrated Visual and Auditory CPT (IVA Plus), Tests of Variables of Attention (TOVA), and Conners' CPT-II.
