Abstract

An oligomer, composition, and composite material employing the same are provided. The oligomer can be a reaction product of a reactant (a) and a reactant (b). The reactant (a) is a reaction product of a reactant (c) and a reactant (d). The reactant (b) can be

or a combination thereof, wherein a is 0 or 1, and R 1 is independently hydrogen or

and wherein b is 0-6; c is 0 or 1; and, d is 0-6. The reactant (c) is

wherein R 2 is C 5-10 alkyl group. The reactant (d) is

wherein e is 0-10.

First claim

What is claimed is:

1. An oligomer, which is a reaction product of a reactant (a) and a reactant (b), wherein the oligomer has a number average molecular weight from 1,000 to 10,000; the reactant (a) is a reaction product or a reactant (c) and a reactant (d), wherein the reactant (c) and reactant (d) are reacted to form reactant (a) prior to the addition of any portion of reactant (b); the reactant (b) is a compound having a structure represented by Formula (I), a compound having a structure represented by Formula (II), a compound having a structure represented by Formula (III), a compound having a structure represented by Formula (IV), or a combination thereof or the reactant (b) is

wherein, a is 0 or 1, and R 1 is independently hydrogen or

 wherein b is 0 or an integer from 1 to 6; c is 0 or 1; d is 0 or an integer from 1 to 6, and at least one of R 1 is not hydrogen; the reactant (c) is a compound having a structure represented by Formula (V), compound having a structure represented by Formula (VI), or a combination thereof

wherein R 2 is independently C 5-10 alkyl group, and the reactant (d) is a compound having a structure represented by Formula (VII)

wherein e is 0 or an integer from 1 to 10.

2. The oligomer as claimed in claim 1 , wherein the weight ratio of the reactant (c) to the reactant (d) is from 1:10 to 10:1.

3. The oligomer as claimed in claim 1 , wherein the weight ratio of the reactant (c) to the reactant (d) is from 1:10 to 1:1.

4. The oligomer as claimed in claim 1 , wherein the weight ratio of the reactant (c) to the reactant (b) is from 1:1 to 20:1.

5. The oligomer as claimed in claim 1 , wherein the weight ratio of the reactant (c) to the reactant (b) is from 1:1 to 10:1.

6. The oligomer as claimed in claim 1 , wherein the reactant (b) is

7. The oligomer as claimed in claim 1 , wherein the reactant (b) is

8. The oligomer as claimed in claim 1 , wherein the reactant (b) is

9. The oligomer as claimed in claim 1 , wherein the reactant (c) is

10. The oligomer as claimed in claim 1 , wherein the reactant (d) is

or a combination thereof.

11. A composition, comprising:
100 parts by weight of the oligomer as claimed in claim 1 ; and
20-110 parts by weight of crosslinking agent.

12. The composition as claimed in claim 11 , wherein the crosslinking agent is ethylene glycol dimethacrylate (EGDMA), 1,4-butanediol diacrylate, triallyl cyanurate, triallyl isocyanurate (TAIC), trimethallyl isocyanurate (TMAIC), butyl acrylate, 2-hydroxyethyl acrylate, diallyl phthalate, diallyl isophthalate, diallyl terephthalate, hydroxypropyl acrylate, 2-hydroxyethyl methacrylate, hydrolyzed polymaleic anhydride, 1,2,4-triallyl trimellitate, divinylbenzene, or a combination thereof.

13. The composition as claimed in claim 11 , further comprising:
1-200 parts by weight of a resin.

14. The composition as claimed in claim 13 , wherein the resin is epoxy resin, cyanate resin, phenol resin, novolac resin, polystyrene resin, styrene-butadiene copolymer resin, polyamide resin, polyimide resin, maleimide, bismaleimide, polyphenylene ether resin, or a combination thereof.

15. The composition as claimed in claim 11 , further comprising:
1-30 parts by weight of an additive.

16. The composition as claimed in claim 15 , wherein the additive is initiator, hardener, leveling agent, filler, colorant, defoamer, flame retardant, or a combination thereof.

17. A composite material, comprising:
a cured product or a semi-cured product prepared by the composition as claimed in claim 11 ; and a substrate, wherein the cured product or the semi-cured product is disposed on the substrate or disposed within the substrate.

18. The composite material as claimed in claim 17 , wherein the substrate is glass fiber, or copper foil.

19. The composite material as claimed in claim 17 , wherein the composite material is copper foil substrate, or a printed circuit board.
