Abstract

PURPOSE: A by-product formed on the purification of bisphenol-A is added to phenol and they are made to react with formaldehyde to a modified phenolic resin that is used as a binder for sand particles giving molds with low expansion on rapid heating for shell mold process.
CONSTITUTION: (A) 100pts. of phenol are combined with (B) 100W1,000pts. of a by- product formed in the course of the purification of bisphenol A from the reaction mixture and the mixture is made to react with (C) formaldehyde in the presence of an acidic or alkaline catalyst by 20W520pts.
