Flame-retardant phenolic resin composition

摘要: PURPOSE: To obtain the title composition outstanding in heat and solvent resistances processability, by incorporating phenolic resin with a mixture of reactive phosphoric ester, non-reactive ester an oligomeric ester. CONSTITUTION: The objective can be obtained 5W30wt.%, based on said resin, made up (A) 22W65wt.% formula I (X is phenyl, cresyl, xylenyl etc.; Y o-, m-, or p-phenylene group; k 0W2, when k=2, two Xs may same not), (B) 15W30wt.% II (C) 5W63wt.% III (Z hydroxyphenyl j are each 0W3; m 0W3).
