| description | PURPOSE:To obtain a modified phenolic resin having a specific softening point by mixing phenol with a specific aromatic hydrocarbon formaldehyde resin at a specific ratio, reacting the components in the presence of an acid catalyst, adding specific amounts of formaldehyde and an alkaline catalyst and reacting under refluxing. CONSTITUTION:The objective modified phenolic resin has a softening point of 65-85 deg.C and excellent heat resistance, moisture-resistance and electrical properties and is suitable as a binder for reinforced material. It can be produced by mixing 100 pts.wt. of phenol with 10-70 pts.wt. of an aromatic hydrocarbon formaldehyde resin containing =14mol/kg, reacting the components with each other in the presence of an acid catalyst (preferably p-toluenesulfonic acid), adding 25-55 pts.wt. of formaldehyde and an alkaline catalyst (preferably sodium hydroxide, etc.), reacting under refluxing and distilling off the unreacted components under reduced pressure. |
