In this paper the shrinkage behaviour of bisphenol‐A‐polycarbonate (PC), polystyrene (PS), poly((ethylene terephthalate)‐co‐(p‐hydroxybenzoate)) liquid crystal polymer (LCP) is illustrated. Moreover, recoil's curves for PC/LCP and PS/LCP blends are shown. The different behaviour found for the two blends investigated is interpreted by taking into account that compatibility can occur between the two phases of the alloys. Moreover, the different physical state (liquid or solid) of the LCP phase at the recoil's temperature analyzed affects considerably its effectiveness in improving the shrinkage hosting matrix behaviour.
