Benzylic ether phenolic resole resins, their preparation, and uses |
| abstract |
This invention relates to benzylic ether phenolic resole resins and the process for preparing them. The benzylic ether phenolic resole resins are prepared by heating phenol and an aldehyde in a sealed reaction vessel in the presence of a divalent metal catalyst without removing water generated by the reaction until an appropriate endpoint for the resin is reached. The benzylic ether phenolic resole resins produced by the process are preferably free or essentially free of unreacted formaldehyde and can be used in the resin component of phenolic-urethane foundry binders to make foundry cores and/or molds by the cold-box and no-bake processes. The cores and/or molds are used for making metal castings. |
