Concerning the nature of molecular movement in epoxy-amine network glassy polymers

The NMR impulse method has been used to study the relaxation properties of a number of model epoxy-polymers based on the diglycidyl ether of resorcinol with various concentrations of crosslinks, degrees of branching and with crosslinking fragments of various types. During glass formation, molecular...

Description
Summary:The NMR impulse method has been used to study the relaxation properties of a number of model epoxy-polymers based on the diglycidyl ether of resorcinol with various concentrations of crosslinks, degrees of branching and with crosslinking fragments of various types. During glass formation, molecular movement in the network polymers is accomplished by segments of at least two types: node with adjacent chain fragments and chain fragments respectively.
