Abstract

A prepolymer is prepared by subjecting a compound of Formula (I) and a vinyl-containing compound to a prepolymerization reaction, and a resin composition includes the prepolymer. The vinyl-containing compound includes bis(vinylphenyl) ethane, divinylbenzene, modification of divinylbenzene or a combination thereof. A ratio in part by weight of the compound of Formula (I) to the vinyl-containing compound in the prepolymerization reaction is 8:2 to 6:4. The resin composition includes the prepolymer and an additive, and an article made from the resin composition may include a resin film, a prepreg, a laminate or a printed circuit board.

First claim

What is claimed is:

1. A prepolymer prepared by subjecting a compound of Formula (I) and a vinyl-containing compound to a prepolymerization reaction,

wherein:
m and n are individually an integer of 1 to 10;
the vinyl-containing compound comprises bis(vinylphenyl) ethane, divinylbenzene, modification of divinylbenzene or a combination thereof; and
a ratio in part by weight of the compound of Formula (I) to the vinyl-containing compound in the prepolymerization reaction is 8:2 to 6:4.

2. The prepolymer of claim 1 , wherein the modification of divinylbenzene comprises a copolymer, a prepolymer or a derivative of the divinylbenzene and a following component: methyl methacrylate resin, triallyl isocyanurate resin, triallyl cyanurate resin, ethylstyrene or a combination thereof.

3. The prepolymer of claim 1 , wherein the prepolymerization reaction is performed in the presence of a reaction initiator, and a content of the reaction initiator is 0.001 to 1 part by weight relative to a total of 100 parts by weight of the compound of Formula (I) and the vinyl-containing compound.

4. The prepolymer of claim 3 , wherein the reaction initiator comprises a Grubbs catalyst, a metal chloride or a combination thereof.

5. The prepolymer of claim 4 , wherein the Grubbs catalyst comprises (1,3-bis-(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(o-isopropoxyphenylmethylene)ruthenium, dichloro(o-isopropoxyphenylmethylene)(tricyclohexylphosphine) ruthenium(II) or a combination thereof.

6. The prepolymer of claim 4 , wherein the metal chloride comprises aluminium chloride.

7. The prepolymer of claim 1 , wherein the prepolymerization reaction has a conversion rate of between 10% and 90%.

8. The prepolymer of claim 1 , wherein the prepolymerization reaction is performed at a temperature of 70 to 120° C. for 1 to 8 hours.

9. A resin composition comprising the prepolymer of claim 1 and an additive.

10. The resin composition of claim 9 , comprising 20 to 108 parts by weight of the additive relative to 100 parts by weight of the prepolymer.

11. The resin composition of claim 9 , wherein the additive comprises polyphenylene ether resin, maleimide resin, vinyl-containing polyolefin resin, hydrogenated polyolefin resin, bis(vinylphenyl) ethane, divinylbenzene, modification of divinylbenzene, triallyl isocyanurate, triallyl cyanurate, styrene copolymer or a combination thereof.

12. The resin composition of claim 9 , further comprising flame retardant, inorganic filler, curing accelerator, solvent, polymerization inhibitor, toughening agent, coupling agent or a combination thereof.

13. An article made from the resin composition of claim 9 , comprising a resin film, a prepreg, a laminate or a printed circuit board.

14. The article of claim 13 , having a dissipation factor at 10 GHz as measured by reference to JIS C2565 of less than or equal to 0.0015.

15. The article of claim 13 , having a glass transition temperature as measured by using a dynamic mechanical analyzer by reference to IPC-TM-650 2.4.24.4 of greater than or equal to 200° C.

16. The article of claim 13 , having a Z-axis coefficient of thermal expansion as measured by using a thermomechanical analyzer by reference to IPC-TM-650 2.4.24.5 of less than or equal to 50 ppm/° C.
