Abstract
PURPOSE: To obtain the titled composition, comprising a condensation product of phenols and dialdehydes, polyepoxy compound and curing catalyst, having excellent heat resistance and mechanical properties, and being useful for varnishes, casting materials, etc.
CONSTITUTION: 1mol Of phenols (A) and 0.1W1.0mol of dialdehydes (B) selected from among glyoxal, glutaraldehyde and telephthalaldehyde are reacted in the presence of an acid catalyst at 40W200°C for 1W6hr to yield a condensation product (a). Then, 100pts.wt. a, 10W250pts.wt. polyepoxy compound (e.g. diglycidil ether of bisphenol A) (b), and 0.1W5pts.wt. of a curing catalyst (e.g. tetraethylammonium chloride) are blended and reacted at 100W200°C to yield a prepolymer (C). Subsequently, said prepolymer is blended with hexamethylenetetramine (D) in an amount of 5W30pts.wt., based on 100pts.wt. of component A.
