Heat resistant thermoplastics resin composition excellent in processing flowability

摘要

A heat resistant thermoplastic resin composition improved in working fluidity while keeping the characteristics of aromatic polyether resins such as heat resistance and solvent cracking resistance. This composition comprises 100 parts by weight of an aromatic polyether resin or a mixed resin of an aromatic polyether resin and a styrene resin and 0.1 to 10 parts by weight of a polyhydric alcohol fatty acid ester having at least one -OH group. This ester preferably has a molecular weight of at least 200.
