We also note what happens when certain polymers are dissolved either in the organic or in the aqueous phase. These results reported in Figure show that the growth of the droplet is arrested, suggesting that that polymers thwart the solubility and/or the diffusion of water from the aueous to the organic phase. This result is corroborated with the the Karl Fisher test (Table , Supplementary Materials) that exhibits undetectable amount of water in organic phase in the presence of such additives. A short summary of what we learned so far is:
