Abstract
Process including steps (a.) through (c.). Step (a.) involves providing a mixture of 41-47 parts by weight phenol component and 54-58 parts by weight formaldehyde. The phenol component in this step is approximately ⅓ by weight para-phenylphenol and ⅔ by weight phenol. Step (b.) involves adding 2-12 parts by weight previously manufactured phenolic resole resin to the mixture formed in step (a.). Step (c.) involves allowing the resulting mixture of phenol, formaldehyde, and phenolic resole resin to react, thereby producing a phenolic resin having a high molecular weight fraction of at least 10 weight-percent. Also, phenolic resole resin made by the process of described herein. Such phenolic resole resin has an average molecular weight that is at least 10% lower and a viscosity that is at least 10% lower than a comparable phenolic resole resin made by carrying out steps (a.) and (c.) in the absence of step (b.) as described herein.
