Abstract
A catalyst for use with a phenolic resins which imparts accelerated curing at reduced temperatures. The catalyst is selected from elemental halogen or opium polyhalide compounds of the general formula: O+X(2n+1)−, where 1≤n≤4, Q is onium group, preferably selected from ammonium, sulfonium and phosphonium; and X is a halide. Each X may be the same or different and may include mixed halides such a X═Br2Cl or Cl2Br.
