Phase domain of microscopic or smaller size, usually in a block, graft, or segmented copolymer, comprising essentially those segments of the polymer that have glass transition temperatures lower than the temperature of use.
Note:
Soft-segment phase domains are often larger than hard-segment phase domains and are often continuous.
