Abstract

The present invention relates to a novel compound having an alkoxysilyl group and an active ester group, a method for preparing the same, a composition comprising the same, and a use, wherein the novel compound exhibits improved low moisture absorption and/or low dielectric properties when cured as an epoxy composition, but is not accompanied by loss of thermal expansion characteristics. Disclosed are a novel compound of formulae AF to LF having an alkoxysilyl group and an active ester group, and a method for preparing the same, a composition comprising the same, and a use of same.

First claim

in Formula FF, -q- is —CH 2 — or a direct linkage,
in Formula GF, r is hydrogen, a hydroxyl group, a C1-C10 alkyl group, or a C1-C10 aromatic group, preferably a C6-C10 aromatic group,
in Formula IF, s is

in Formula LF, t is

in Formulae IF to LF, n is an integer equal to or greater than 1,
in Formulae AF to EF, at least one of a plurality of Ps is —(CH 2 )mSiRaRbRc, at least one of Ra, Rb, and Rc is a C1-C5 alkoxy group and the remainders thereof are alkyl groups having 1 to 10 carbon atoms, the alkyl group and the alkoxy group are a linear or branched alkyl group and a linear or branched alkoxy group, m is an integer ranging from 3 to 10, the remainders thereof are hydrogen or alkenyl group of —(CH 2 ) l CHCH 2 , where l is an integer ranging from 1 to 8,
at least one of a plurality of Qs is —COR 1 , where R 1 is an aliphatic, alicyclic, or aromatic hydrocarbon group of C1-C20, and the aliphatic hydrocarbon group is a linear or branched aliphatic hydrocarbon group, and the remainder of the plurality of Qs are hydrogen,
in Formulae FF to LF, at least one of a plurality of Rs is —(CH 2 )mSiRaRbRc or —CONH(CH 2 )mSiRaRbRc, where at least one of Ra, Rb, and Rc is a C1-C5 alkoxy group, and the remainders thereof are alkyl groups having 1 to 10 carbon atoms, the alkyl group and the alkoxy group are linear or branched, m is an integer ranging from 3 to 10, at least one of a plurality of Rs is —COR 1 , R 1 is an aliphatic, alicyclic, or aromatic hydrocarbon group of C1-C20, the aliphatic hydrocarbon group is linear or branched, and the remainder of the plurality of Rs are hydrogen or alkenyl group of —(CH 2 ) l CHCH 2 , independently, where l is an integer ranging from 1 to 8.

2. An epoxy composition comprising a compound having an alkoxysilyl group and an active ester group selected from a group consisting of Formulae AF to LF of claim 1 .

3. The epoxy composition of claim 2 , further comprising:
an epoxy compound, a curing agent, and a filler.

4. An electrical and electronic material including the epoxy composition of claim 2 .

5. The electrical and electronic material of claim 4 , wherein the electrical and electronic material is a substrate, a film, a laminated substrate, prepreg, a printed circuit board, or a packaging material.
