Heterogeneous structure ofcis‐isoprene rubber and oligodiene diisocyanate blends

摘要

AbstractThe structural peculiarities ofcis‐1,4‐isoprene rubber, oligodiene diisocyanate, and derivative of phenol–formaldehyde resin blends have been studied by WAXS and SAXS methods and electron microscopy. It has been demonstrated that the addition of modifiers and further thermal treatment under conventional curing conditions change considerably the microheterogeneous structure and morphology and contribute to the improvement of the short‐range order in the rubber
