21. Control measurements of our crosslinked films, similar to the procedure described in ref. 20, showed typical crosslink densities of 4-8 crosslink points per chain.
22. AFM measurements showed surface roughnesses of a few nanometers for crosslinked films compared to typically 1-2 nm for as-cast, noncrosslinked films (ref. 20).

24. x/y are the different Hamaker constants. Thus, for the liquid polyolefin mixture on top of a d = 200-nm thick crosslinked polyolefine film, the interactions (at say the midplane of the film at h = 200 nm) are largely due to the crosslinked film and not to the underlying silicon substrate.

30. The slightly broadened edges at the two confining surfaces (D = 185 nm and 615 nm) in Figure 4(a) suggest that the extent of crosslinking was not quite sufficient (see Experimental), so that some slight interdiffusion took place at the xh86 walls.

34. The study of ref. 14 indeed shows, optically, a lateral array of phase-separated regions, presumed to be of one phase coated by the other, when the phase-separated mixture is symmetrically confined.
