Abstract
Official abstract text for this publication.
A resin composition having a high thermal aging property and molding stability in mass production of molded articles while keeping molding fluidity and thermal creep resistance is provided. A resin composition, containing 100 parts by mass in total of a polypropylene resin (a) and a polyphenylene ether resin (b), and 1 to 20 parts by mass of a compatibilizer (c), wherein in the component (a), the proportion of the component having a molecular weight of 30,000 or less is from 3.0 to 5.1% of the entire component (a), and the proportion of the component having a molecular weight of 10,000,000 or more is from 1.0 to 1.6% of the entire component (a).
First claim
Opening claim text (preview).
What is claimed is: 1. A resin composition, comprising: 100 parts by mass in total of a polypropylene resin (a) and a polyphenylene ether resin (b), and 1 to 20 parts by mass of a compatibilizer (c), wherein in the component (a), a proportion of a component having a molecular weight of 30,000 or less, which is determined by gel permeation chromatography (GPC, mobile phase: o-dichlorobenzene, standard substance: polystyrene), is from 3.0 to 5.1% of the entire component (a), a…
