Abstract
PURPOSE: To obtain a modified flame-retardant phenolic resin suitable for a laminate having improved impact resistance stably, by using a diepoxy compound of specific structure as a plasticizing modifier for a resol phenolic resin.
CONSTITUTION: (B) A compound expressed by formula I [at least one of Z and Z' is formula II (X is Br or Cl), the other is formula II, ethylene, propylene or a combination of 2W18 thereof via an O atom] in an amount of preferably 10W200g per mole of a phenol constituting the component (A) is added to (A) a resol phenolic resin or the system of preparing the resin.
