ABSTRACT:
In a process of curing solution-polymerized synthetic rubbers, the improvement effected is the retardation of the cure rate and increasing of time to scorch by the addition of small amounts of a heat-curable phenol-formaldehyde resin. This method of controlling cure rate and scorch time complements other techniques known in the art (e.g., cure accelerators), and can be used to adjust the properties of solution-polymerized rubbers to match those of emulsion-polymerized rubbers.
