Patent ID: 8268938

Claim:
A composition for forming a board, comprising: a monomeric maleimide-based compound including at least three maleimide groups, wherein the maleimide-based compound comprises a compound represented by the following Chemical Formula 1 or 2, or a combination thereof: wherein, in the above Chemical Formulae 1 and 2, R 1 to R 3 are independently a substituted or unsubstituted C6 to C24 arylene, R 4 and to R 7 are independently hydrogen or a C1 to C5 alkyl, Y 1 and Y 2 are independently C(═O)O, C(═O)NH, O, CO, or a combination thereof, and n 1 and n 2 are independently integers being from 3 to 5, provided that when n 1 is 3, X 1 is CR, P(═O), SiR, SiOR, or a combination thereof, where R is hydrogen or a C1 to C5 alkyl; when n 1 is 4, X 1 is C, Si, SiO, or a combination thereof; when n 1 is 5, X 1 is P, and when n 2 is 3, X 2 is CR, P(═O), SiR, SiOR, or a combination thereof, where R is hydrogen or a C1 to C5 alkyl; when n is 4, X 2 is C, Si, SiO, or a combination thereof; and when n 2 is 5, X 2 is P; and a liquid crystalline polymer or liquid crystalline oligomer.
