Synthesis and properties of phenol-starch resin

The one-step synthesis of a new phenol-starch resin by polycondensation with phenol, starch as raw materials under catalysis of sulfuric acid is introduced.The synthetic reaction mechanism and the resin structure are characterized, the effects of amount of catalyst, technological parameters (total reaction time, highest reaction temperature) and raw material ratio (phenol/starch) on the product are discussed.The typical raw materials formula, synthetic technological route and technological parameters are determined, the analysis of the properties and the beneficial superiority is conducted. Results show that phenol-starch resin belongs to thermoplastic phenolic resin, it is similar in the properties to the thermoplastic phenol-formaldehyde resin, specially it has very good heat resisting property, and the economic and environmental beneficial superiority is obvious.
