STUDY OF COMPOSITION OF PHENOL-FORMALDEHYDE OLIGOMERS BY NEPHELOMETRIC METHOD

Currently, phenol-formaldehyde oligomers cross-composite with various thermoplastic oligomers and monomers are well used in many fields, including: as binders in obtaining composite materials, as coating formers, in the production of plastic products and in other fields. is bearing fruit. In this case, the best way to confirm that the obtained oligomers are sooligomers is to study them by nephelometric titration.
