Fire retardant polymer resin |
摘要 |
Flame retardant polymer resins formed by an acid condensation reaction from a mixture of resorcinol and furfural with a molar excess of the aldehyde. In one particular embodiment the resin is formed of a mixture of two prepolymer solutions with at least a boric acid catalyst, one or both of the prepolymer solutions being an acid-condensation reaction product of resorcinol and furfural with excess aldehyde functionality, or one of the prepolymers being a mix of substantially unreacted resorcinol and furfural with a slight molar excess of aldehyde.
