ON THEIR COMPATIBILITY

Consideration is given to a melt of rigid rod-like macromolecules 
whose side main-chain links are capable of associating with active 
end groups of flexible chains (it is assumed that each flexible chain 
has only one active end group), thus forming associated complexes. 
It is shown that with decrease in the temperature the association 
facilitates substantial improvement in the compatibility of rigid 
and flexible molecules in the melt.
