Abstract
Abstract This invention relates to a new and improved resin composition containing polyphenylene ether and, more particularly, to a molding resin composition including polyphenylene ether and cyclopentadiene resin containing a polar group. The new and improved resin composition has good melting flowability and retains good mechanical and thermal characteristics inherent to polyphenylene ether and can be suitably used as a molding material.
