Abstract

A resin composition includes 120 parts by weight of a vinyl group-containing polyphenylene ether resin, 5 parts by weight to 10 parts by weight of a compound of Formula (1), 15 parts by weight to 25 parts by weight of a compound of Formula (2), and 70 parts by weight to 110 parts by weight of an inorganic filler. The resin composition may be used to make various articles, such as a prepreg, a resin film, a laminate or a printed circuit board, and at least one of the following properties can be improved, including difference rate of dissipation factor, gel time stability and stickiness.

First claim

What is claimed is:

1 . A resin composition, comprising 120 parts by weight of a vinyl group-containing polyphenylene ether resin, 5 parts by weight to 10 parts by weight of a compound of Formula (1), 15 parts by weight to 25 parts by weight of a compound of Formula (2), and 70 parts by weight to 110 parts by weight of an inorganic filler,

wherein X is —(CH 2 ) n CH 3 or —C(CH 3 )═CH 2 , and n is 13;

wherein k is an integer of 1 to 10.

2 . The resin composition of claim 1 , wherein the vinyl group-containing polyphenylene ether resin comprises a vinylbenzyl group-containing biphenyl polyphenylene ether resin, a methacrylate group-containing polyphenylene ether resin or a combination thereof.

3 . The resin composition of claim 1 , wherein the inorganic filler comprises chemically synthesized silica, fused silica, boron nitride or a combination thereof.

4 . The resin composition of claim 1 , further comprising bis(vinylphenyl)ethane, maleimide resin, or a combination thereof.

5 . The resin composition of claim 1 , further comprising curing accelerator, flame retardant, polymerization inhibitor, solvent, coloring agent, toughening agent or a combination thereof.

6 . An article made from the resin composition of claim 1 , comprising a prepreg, a resin film, a laminate or a printed circuit board.

7 . The article of claim 6 , having a difference rate of dissipation factor of less than or equal to 4.10% calculated according to a dissipation factor as measured by reference to IPC-TM-650 2.5.5.13 at 10 GHz.

8 . The article of claim 6 , having a gel time stability calculated according to a gel time as measured by reference to IPC-TM-650 2.3.18 of less than or equal to 18 seconds.

9 . The article of claim 6 , characterized by passing a level 1 stickiness test.
