Conventional GPC of Phenolic Resins on ResiPore Columns

Polymer Laboratories' latest technical bulletin describes the examination of Phenolic Resins Conventional by means of GPC. The term "phenolic resin" is used to describe a group of thermosetting resins produced through the reaction of phenol with an aldehyde. Phenolic resins were the earliest synthetic polymers to be developed (Bakelite, 1907), and possess useful mechanical and physical properties. Applications of phenolic resins include electrical insulation, moulding, lamination and adhesives. Key characteristics of phenolic resins are their molecular weight distribution and oligomeric "fingerprint" as these both have significant effects on the end use properties of the resin.
GPC is an ideal analytical tool for the examination of both of these characteristics. In this case, the use of high resolution GPC columns is advantageous, since these allow an optimized oligomeric separation and provide detailed information regarding the oligomeric sample composition.
