Abstract
The present invention provides a resin composition comprising maleimide-containing pre-polymerized resin and article made therefrom. The resin composition comprises: 100 weight parts of vinyl-containing polyphenylene ether resin; 35 to 45 weight parts of bis(vinylphenyl)ethane; and 30 to 60 weight parts of maleimide-containing pre-polymerized resin; wherein the maleimide-containing pre-polymerized resin is obtained by pre-polymerization of aromatic maleimide resin and long chain maleimide resin. The articles made from the resin composition improve at least one characteristic of glass transition temperature variation, copper foil peeling strength, percentage of thermal expansion, coefficient of thermal expansion and surface appearance.
Claims9
A resin composition comprising maleimide-containing pre-polymerized resin comprising:
- 100 parts by weight of vinyl-containing polyphenylene ether resin;
