Title:
POLY(VINYL BENZYL) ETHER COMPOUND, METHOD FOR PRODUCING SAME, CURABLE COMPOSITION CONTAINING SAME, AND CURED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2014/103926
Kind Code:
A1
Abstract:
Provided are: a poly(vinyl benzyl) ether compound which can have high dielectric properties (a low dielectric constant, a low dielectric tangent) even after undergoing a thermal history at a high temperature and enables the production of a cured article having a high glass transition temperature and high flame retardancy; and a curable composition.
A poly(vinyl benzyl) ether compound produced by reacting a naphthol aralkyl resin with a vinyl aromatic halomethyl compound, said poly(vinyl benzyl) ether compound being characterized by having a total halogen content of 600 ppm or less, and also having a ratio of a peak area derived from the vinyl aromatic halomethyl compound to the total peak area, which is the sum total of the peak area derived from the vinyl aromatic halomethyl compound and a peak area derived from the poly(vinyl benzyl) ether compound, is 1.0% or less as measured by gel permeation chromatography.
