36. 3. Assuming that this sphere consists of a core of homo PS and a shell of the block copolymer of a thickness equal to the half thickness of the vesicle wall, i.e., 15 nm, we calculate the B/R ratio as 81:19 w/w, which is close to the experimental B/R ratio of 80:20 w/w. We can thus conclude that the spheres consist of homo PS surrounded by a layer of block copolymer.
37. 3. Thus the diameter of the sphere inside the cavity is calculated to be ca. 30 nm, which is consistent with the experimental value.
38. This value of 2 nm was obtained from a change in size over a much larger range of water contents. The initial range was from 15 to 50 wt%, but only the 15 to 20 wt % range is mentioned here for comparison with the data reported in the following paragraph.
