Abstract: PURPOSE:To obtain a flame-retarding resin composition suitable for printed wiring and excellent in high-frequency characteristics and heat resistance by mixing a specified epoxidized butadiene polymer with tetrabromobisphenol A and a specified compound. CONSTITUTION:A flame-retarding resin composition is obtained by mixing an epoxidized butadiene polymer (A) of an epoxy content >=0.3mol per 100g obtained by epoxidizing a butadiene polymer of a 1, 2 bond content >=50% with tetrabromobisphenol A (B) and a compound (C) of the formula (wherein R1, R2 and R3 are each H or CH3). By using polymer A, a prepreg of excellent moldability can be obtained. Because both polymer A and compound C have epoxys which are polar groups, a metal foil-clad laminate of a high peeling strength of a metal foil can be obtained. Because compound C has an epoxy on one molecular end and has a double bond on the other end, this compound reacts with the double bond of polymer A to increase the crosslinking density to better the heat resistance, and because bromine atoms are introduced into the molecule, the flame retardancy can be kept on a sufficient level.
