摘要

PROBLEM TO BE SOLVED: To provide a resin composition with low permittivity and dielectric loss tangent, providing a flame-retardant cured product, and a prepreg, a laminated sheet and a multilayer printed circuit board prepared by using it. ;SOLUTION: The resin composition comprises a cross-liking component with a wt. average molecular wt. of 1,000 or less and having a multifunctional styrene group of formula 1 (wherein R is an optionally substituted hydrocarbon; R², R³ and R⁴ are each a H atom or a 1-6C hydrocarbon group; R⁵, R⁶, R⁷ and R⁸ are each a H atom or a 1-20C hydrocarbon group; and n is an integer of 2 or more) and a bromine compound, used for preparation of the prepreg, the laminated sheet and the multilayer printed circuit board.;COPYRIGHT: (C)2004,JPO
