ABSTRACT:
There is provided thermosetting resin compositions suitable for injection molding compounds having an apparent curing rate of 0.7 and 0.008 cm/sec respectively at 170.degree. C. and 110.degree. C. by a disk cure tester and an apparent activation energy of at least 26 Kcal/mol, by the addition of fluidity modifiers selected from ether compounds having methylene ether type structure, ester compounds having methylene groups connected with carbonyl ether groups and alcohol compounds having methylene groups connected with hydroxyl groups, to phenolic resin, hexamethylenetetramine, fillers and additives.
