Structure and performance of hydrazine-containing polyurethane thermoplastic elastomers

Structure and performance of hydrazine-containing polyurethane thermoplastic elastomers 

The structure and properties of polyurethane thermoplastic elastomers that are block copolymers of the [AB] type are mainly determined by the chemical structure of the macromolecule and by the intermolecular bonds in the system where the soft and hard blocks exist as thermodynamically incompatible microphases. The effect of the macromolecular structure on the properties of the polymers obtained is discussed in this section. 

Macrochain structure and supramolecular organization of hydrazine-containing polyurethane elastomers 

In this section, two non-trivial and rarely discussed polymer types are considered polyurethanes based on asymmetric dimethylhydrazine and polyurethanes based on the hydrazides of macroheterocylic compounds.
