Abstract

The disclosure relates to a phosphorus-containing vinyl polyphenylene ether obtained by reacting a phosphorus-containing vinyl compound with a vinyl polyphenylene ether, a resin composition including the phosphorus-containing vinyl polyphenylene ether and a product thereof. Various products can be made from the resin composition, such as resin films, prepregs, resin-coated coppers, laminates or printed circuit boards, and they have one, multiple or all of the following properties: lower coefficient of thermal expansion, lower thermal expansion, higher thermal resistance, better flame retardancy, lower dielectric constant, lower dielectric loss and so forth.

First claim

What is claimed is:

1. A phosphorus-containing vinyl polyphenylene ether produced by a process comprising reacting a phosphorus-containing vinyl compound with a vinyl polyphenylene ether.

2. The phosphorus-containing vinyl polyphenylene ether according to claim 1 , wherein the phosphorus-containing vinyl compound comprises an allyl phosphazene compound, a vinylbenzyl ether phosphazene compound, a vinyl phosphonate compound, an acrylate DOPO compound or a combination thereof.

3. The phosphorus-containing vinyl polyphenylene ether according to claim 2 , wherein the phosphorus-containing vinyl compound comprises an allyl phosphazene compound having the following structural unit:

wherein n is an interger of 1 to 6.

4. The phosphorus-containing vinyl polyphenylene ether according to claim 2 , wherein the phosphorus-containing vinyl compound comprises a vinylbenzyl ether phosphazene compound having the following structural unit:

wherein n is an interger of 1 to 6.

5. The phosphorus-containing vinyl polyphenylene ether according to claim 1 , wherein the vinyl polyphenylene ether comprises methacrylate polyphenylene ether, vinylbenzyl polyphenylene ether, chain-extended polyphenylene ether or a combination thereof.

6. A resin composition, comprising the phosphorus-containing vinyl polyphenylene ether according to claim 1 and at least one crosslinking agent.

7. The resin composition according to claim 6 , wherein the crosslinking agent comprises divinylbenzene, bis(vinylphenyl) ether, isocyanate, polyphenylene ether resin, maleimide, polyamide, polyimide, styrene maleic anhydride copolymer, polyester, polyolefin, anhydride curing agent or a combination thereof.

8. The resin composition according to claim 6 , further comprising any one of a phosphorus-containing flame retardant, a curing accelerator, an inorganic filler, a surfactant, a toughening agent, a solvent and a combination thereof.

9. The resin composition according to claim 6 , further comprising a second polyphenylene ether.

10. The resin composition according to claim 9 , wherein based on 100 parts by weight of the total amount of the resin composition, the content of the phosphorus-containing vinyl polyphenylene ether ranges from 50 to 100 parts by weight.

11. The resin composition according to claim 9 , wherein based on 100 parts by weight of the total amount of the resin composition, the content of the second polyphenylene ether ranges from 0 to 50 parts by weight.

12. A product made from the resin composition according to claim 6 , comprising a resin film, a prepreg, a resin-coated copper, a laminate or a printed circuit board.

13. The product according to claim 12 , having a Z-axis coefficient of thermal expansion α1 as measured by a TMA instrument by reference to IPC-TM-650 2.4.24.5 of lower than or equal to 50 ppm/° C.

14. The product according to claim 12 , having a Z-axis thermal expansion as measured by a TMA instrument by reference to IPC-TM-650 2.4.24.5 of lower than or equal to 2.9%.

15. The product according to claim 12 , having a thermal resistance T288 as measured by a TMA instrument by reference to IPC-TM-650 2.4.24.1 of greater than 70 minutes.

16. The product according to claim 12 , having a flame retardancy of UL94 V0 or V1.
