Abstract
A phosphazene compound having a vinyl group is manufactured by a reaction between a vinyl compound and a phosphazene compound having a hydroxyl group and added to a resin composition for manufacturing a prepreg or a resin film so as to be applicable to copper-clad laminates and printed circuit boards to thereby achieve satisfactory circuit laminate properties, namely low coefficient of thermal expansion, low dielectric properties, heat resistant, fire resistant, and halogen-free.
Claims10
A phosphazene compound having a vinyl group, with the phosphazene compound being of a structure expressed by formula (II) below:
- formula (II),
- wherein the structure of formula (II) is cyclic and n denotes an integer from 3 to 6.
A method for manufacturing a phosphazene compound having a vinyl group, characterized in that the phosphazene compound having a vinyl group is manufactured by a reaction between a vinyl compound and a phosphazene compound having a hydroxyl group, wherein the vinyl compound is selected from the group consisting of 4-chloro-methyl styrene, 3-chloro-methyl styrene, and 2-chloro-methyl styrene.
A method for manufacturing a phosphazene compound having a vinyl group, characterized in that the phosphazene compound having a vinyl group is manufactured by a reaction between a vinyl compound and a phosphazene compound having a hydroxyl group, wherein the reaction takes place in the presence of sodium hydroxide and tetrabutylammonium iodide.
