Abstract
Abstract
It can thus be concluded that phase heterogeneity in rubber blends almost always prevails and can be shown by means of microscopy. Compatibilization of these blends, as judged by the emergence of intermediate dynamic loss peaks, can be achieved through a vulcanization process which promotes crosslinks between the heterogeneous polymer phases. Such compatibilization through interphase crosslinking can occur even with polymers of significantly different solubility parameters. Interphase crosslinking can be recognized from swelling restriction in the differential swelling test but also from the development of intermediate dynamic loss peaks. The development of interphase crosslinks, therefore, results in the formation of a new copolymer system from the two mixed components which has new and unique properties. The requirements of cure systems which promote cocuring of polymer phases are not fully understood. Important factors to be considered are curative migration; however, a discussion of this subject would be beyond the scope of this presentation.
