| Summary: | The role of switching segments on the shape memory property of epoxy-cyanate ester
system was investigated. The shape memory thermoset polymer was designed by co-reacting
cyanate ester and epoxy with phenol-telechelic of different switching segments constituted by
poly(tetramethyleneoxide) (PTMO), poly(ε-caprolactone) (PCL) and poly(propylene) (PPG).
Phenol groups help the shape memory component get integrated into the network matrix
through coreaction with both cyanate and epoxy groups. All polymer possessed good
mechanical properties and thermal stability. The PTMO system is a good as the PCL system
in terms of shape memory properties. Vis-a-vis to the alcohol terminated shape memory
component, phenol terminal groups help the PTMO segments get integrated into the matrix.
The resin is suited to process good elastic memory composites as cyanate esters normally
promote excellent composite formation. |
