Polyphenylene ether resin

摘要

A resin composition comprising a polyphenylene ether resin and a rubber-modified polystyrene resin, wherein at least 80% of the rubber particles based on the total number of rubber particles in the elastomeric phase of the rubber-modified polystyrene resin have a particle diameter in the range of 0.5 to 4 microns, and the elastomeric phase has a particle size distribution index, SDI, defined by the equation wherein x is the diameter in microns of the particles, and n is the number of particles having a particle diameter of x microns, of not more than 1.9.
