Abstract

An investigation has been undertaken to assess the effectiveness of the chemical probe technique in identifying the susceptibility of complex polymeric mouldings to environment stress cracking (ESC). PMMA samples were produced with weld-line defects using a double-gated mould. The variation in relative ESC susceptibility of the weld-line with distance from the gates was readily identified by the chemical probe technique. In addition, quenched and air-cooled samples were easily distinguished. It is envisaged that the chemical probe technique could be used to detect poorly processed samples with respect to ESC susceptibility.
