Abstract

PURPOSE: To prepare a flame-retardant phenolic resin having high stability and excellent impact resistance, by using a halogenated polyether having a specific structure as a modifier for plasticization of a phenolic resin, together with a flame retardant.
CONSTITUTION: (A) A halogenated polyether having phenol nucleus at one or both chain ends [e.g. formula I (m and m' are positive number or one of them is 0; R1 is 5W20C alkoxy, 4W15C alkyl-substituted phenyl, etc.; R2 is formula II or III; R3WR6 are H, methyl, bromomethyl or chloromethyl)] is added as a modifier for plasticization to (B) a resol-type phenolic resin or its raw materials. (C) A flame retardant (e.g. antimony trioxide, tetrabromoethane, etc.) is further added to the mixture. The preferable amount of (A) is 10W200g on the basis of 1mol of the charged phenol for preparation of (B).
