N2 - DDFT is applied to phase formation in homopolymer/copolymer blends in which the copolymer
is extremely disperse with a uniform chemical composition distribution. Such systems
develop a core/shell structure with a thick interface. This study is motivated by peculiarities in
the phase evolution of industrial PP high-impact copolymers. It is demonstrated that it is
possible to reach time and length scales of relevance for realistic industrial blend systems. A
rational method for improving the numerical efficiency of the calculations is presented. The
model can be applied to a variety of industrially
relevant systems with similar ‘‘random chemistry’’
or extreme copolymer dispersity in coatings,
crude oil recovery systems, food emulsions,
and so forth.
