A nitrogen-modified flame-retardant resin composition and the

The present invention is an aldehyde to phenolic compound under a basic catalyst compound and reacted to obtain by reacting a phosphorus-based flame retardant and again melamine after producing the resole resin and then the, nitrogen-modified, characterized in that of the formula (3) flame-retardant resin and that It relates to a composition, which has excellent flame retardancy as well as mechanical and electrical properties of advantages. [Formula 3] (In the formula 3 X it may be represented by the following general formula (1) or (2).) Formula 1 (Wherein R and n, m is any integer of 1 to 12, R1: is any one or more of each independently hydrogen (H) or alkyl group or a phenyl group, a cumyl group, an alkoxy group of C1 ~ C10. [Formula 2] (Wherein R and n, m is any integer of 1 to 12, Y is each independently is a sulfonyl group, any one or more of the alkyl group of an unsubstituted alkylidene group, or C1 ~ C10.)
