Figure 2 shows the range of the nematic-isotropic heterophasic behaviour and its consequences on the nematic order parameter S T) for... 

Although it is reasonable to expect differences in degradation behaviour between random and heterophase copolymers, literature seldom defines clearly the nature of copolymers studied. Well characterized heterophase E-P copolymers, however, are of very recent origin. 

The difficulty in generalizing heterophase free radical polymerizations is not surprising given the large variation in physical and chemical behaviour present in relatively uncomplicated homogeneous processes such as bulk or solution polymerizations...

Thus, under some conditions, the composite models can be successfully applied to the description of the behaviour of amorphous and semi-crystalline polymers within the frameworks of the quasi-two-phase cluster model. In this case, an obvious possibility for obtaining quantitative correspondence between theory and experiment exists under the condition of heterophase structure of amorphous state and the accuracy of the cluster model [41].
