Semi-interpenetrating networks have been produced from castor oil and
poly(ethylene terephthalate) (PET). Bond interchange between PET and c
astor oil plays a major role in the development of initial miscibility
, also affecting morphology and chemical structure. Microheterogeneous
morphology is developed for materials of intermediate composition, wh
ich have much greater toughness than the polymers from which they were
made.
