CURING OF WATER-CONTAINING UNSATURATED POLYESTER RESINS INVOLVING A COBALT ACCELERATOR AND A COMPLEXING COMPOUND

摘要

The present invention relates to a process for curing an unsaturated polyester resin wherein the unsaturatedpolyester resin comprises at least 0.15 percent by weight of water, and 0.02 to 5.0 percent by weight of one or more conventional radical initiators comprising a -OOH moiety, at least 5 ppm of a cobalt accelerator, and at least one complexing compound, all percentages being based on the weight of the polyester resin. Furthermore it relates to the cured articles obtained using such a process.
