Abstract

The present invention discloses vinyl-modified maleimide, a resin composition using the same and a preparation thereof. The vinyl-modified maleimide has better solvent selectivity and solvent compatibility. The obtained preparation can satisfy the properties of no crack between multilayer boards and high frequency and low dielectric properties maintained after moisture absorption.

First claim

What is claimed is:

1. A vinyl-modified maleimide made from the reaction of 4-vinylbenzyl amine with aliphatic long chain maleimide, wherein the aliphatic long chain maleimide comprises an aliphatic long chain maleimide having a structure unit represented by one of the following formula (6) and formula (7)

wherein n=1 to 10; or

wherein n=1 to 10, and the reaction ratio (part by weight) of the 4-vinylbenzyl amine to the aliphatic long chain maleimide is 20:80 to 35:65.

2. A resin composition, comprising the vinyl-modified maleimide of claim 1 and at least one cross-linking agent.

3. The resin composition of claim 2 , wherein the cross-linking agent comprises at least one of divinylbenzene, bis(vinylbenzyl) ether, 1,2-bis(vinylphenyl)ethane, triallyl isocyanurate, triallyl cyanurate, cyanate ester, isocyanate ester, 1,2,4-trivinylcyclohexane, styrene, acrylate, polyphenylene oxide resin, polyamide, polyimide, styrene maleic anhydride copolymer, polyester, an olefin polymer, an epoxy resin and an anhydride curing agent, a prepolymer or a combination thereof.

4. The resin composition of claim 2 , further comprising a flame retardant, a curing accelerator, an inorganic filler, a surfactant, a toughener, a solvent or a combination thereof.

5. The resin composition of claim 2 , wherein the resin composition comprises 100 parts by weight of the vinyl-modified maleimide and 1 to 500 parts by weight of the cross-linking agent.

6. An article made from the resin composition of claim 2 , comprising a resin film, a prepreg, a resin coated copper, a laminate or a printed circuit board.
