Abstract

A resin composition comprises: a vinyl-containing polyphenylene ether resin, a bis(vinylphenyl)ethane and a modification of divinylbenzene. 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 achieves improvements in at least one of the properties including dielectric constant, dissipation factor, copper foil peeling strength, glass transition temperature, ratio of thermal expansion, thermal expansion coefficient, precipitation property of varnish, solder dipping thermal resistance, solder floating thermal resistance of multi-layer board, reflow thermal resistance of multi-layer board and T300 thermal resistance.

First claim

What is claimed is:

2. The resin composition of claim 1 , wherein the vinyl-containing polyphenylene ether resin comprises a vinylbenzyl-containing polyphenylene ether resin, a methacrylate-containing polyphenylene ether resin, an allyl-containing polyphenylene ether resin, a vinylbenzyl-modified bisphenol A polyphenylene ether resin, a chain-extended vinyl-containing polyphenylene ether resin or a combination thereof.

3. The resin composition of claim 1 , wherein the bis(vinylphenyl)ethane comprises 1,2-bis(4-vinylphenyl)ethane, 1,2-(3-vinylphenyl-4-vinylphenyl)ethane, 1,2-bis(3-vinylphenyl)ethane or a combination thereof.

4. The resin composition of claim 1 , further comprising: a maleimide resin, a small molecule vinyl compound, an acrylate, an epoxy resin, a cyanate ester resin, a phenolic resin, a benzoxazine resin, a styrene maleic anhydride, a polyolefin, a polyester resin, an amine curing agent, a polyamide resin, a polyimide resin or a combination thereof.

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

6. The resin composition of claim 1 , comprising 50 parts by weight of the vinyl-containing polyphenylene ether resin, 5 to 40 parts by weight of the bis(vinylphenyl)ethane and 2 to 20 parts by weight of the modification of divinylbenzene.

7. The resin composition of claim 1 , comprising 50 parts by weight of the vinyl-containing polyphenylene ether resin, 10 to 30 parts by weight of the bis(vinylphenyl)ethane and 5 to 15 parts by weight of the modification of divinylbenzene.

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

9. The article of claim 8 , having a dielectric constant and a dissipation factor at 10 GHz as measured by reference to JIS C2565 of less than or equal to 3.15 and of less than or equal to 0.0020 respectively.

10. The article of claim 8 , having a copper foil peeling strength as measured by reference to IPC-TM-650 2.4.8 of greater than or equal to 3.00 lb/in.

11. The article of claim 8 , having a glass transition temperature as measured by reference to IPC-TM-650 2.4.24.4 of greater than or equal to 200° C.

12. The article of claim 8 , having a ratio of thermal expansion as measured by reference to IPC-TM-650 2.4.24.5 of less than or equal to 2.50%.

13. The article of claim 8 , having a thermal expansion coefficient as measured by reference to IPC-TM-650 2.4.24.5 of less than or equal to 55 ppm/° C.

14. The article of claim 8 , characterized in that no delamination occurs after subjecting the article to a solder dipping thermal resistance test of more than 20 cycles by reference to IPC-TM-650 2.4.23.

15. The article of claim 8 , characterized in that no delamination occurs after subjecting the article to a solder floating thermal resistance test of multi-layer board of 20 cycles by reference to IPC-TM-650 2.4.13.1.

16. The article of claim 8 , characterized in that no delamination occurs after subjecting the article to a 260° C. reflow thermal resistance test of multi-layer board of 10 cycles by reference to IPC-TM-650 2.6.27.

17. The article of claim 8 , having a T300 thermal resistance as measured by reference to IPC-TM-650 2.4.24.1 of greater than 75 minutes.
