**Abstract**
 Co-reaction of epoxy resin with a partially propargylated novolac resulted in a dual cure resin system with improved processability. The resin system showed moderately good adhesion strength, which was optimised for a phenol/epoxy equivalent ratio of 2:1. Good retention of properties was observed for the dual-cure system at 100 degrees C. Replacement of the novolac epoxy with diglycidyl ether of bisphenol-A resulted in enhanced adhesion. Co-curing with epoxy led to ease of processing without affecting the mechanical characteristics of the resultant glass composites. Minimisation of the epoxy content was needed in order to avoid sacrificing the thermal characteristics and Tg of the system. 17 refs.
