| The reaction of a polyurethane/poly((styrene)-co-(vinyl ester)) interpenetrating polymer network (PU/P(St-co-VE)-IPN) and its constituent polymers were studied by FTIR, DSC, and gel time measurements. PU network was composed of polyether diol, triol, 1,4-butane diol and MDI. P(St-co-VE) network was composed of styrene and epoxy novolak-based vinyl ester. The chemical and physical effects on the physical properties and morphology of the IPN were investigated by DMA, DSC, TMA, optical microscopy and impact strength testing. It was found that the components of the IPN system investigated were compatible with each other at 100... |
