Abstract

The present invention aims to provide a resin composition capable of providing a molded article which is excellent in flexibility, acid resistance, and electrical properties. The resin composition of the present invention includes: an aromatic polyether ketone resin (I); and a fluororesin (II), the fluororesin (II) being a copolymer of tetrafluoroethylene and a perfluoroethylenic unsaturated compound represented by the following formula (1): CF 2 ═CF—Rf 1 (1) wherein Rf 1 represents —CF 3 or —ORf 2 , and Rf 2 represents a C 1 -C 5 perfluoroalkyl group, the fluororesin (II) being dispersed as particles in the aromatic polyether ketone resin (I), the resin composition satisfying a ratio (I):(II) by mass between the aromatic polyether ketone resin (I) and the fluororesin (II) of 50:50 to 10:90.

First claim

The invention claimed is:

1. A resin composition consisting of:
an aromatic polyether ketone resin (I); and
a fluororesin (II),
the fluororesin (II) being a copolymer of tetrafluoroethylene and a perfluoroethylenic unsaturated compound represented by the following formula (1):
CF 2 ═CF—Rf 1   (1)

wherein Rf 1 represents —CF 3 or —ORf 2 , and Rf 2 represents a C 1 -C 5 perfluoroalkyl group,
the fluororesin (II) being dispersed as particles in the aromatic polyether ketone resin (I),
the resin composition satisfying a ratio (I):(II) by mass between the aromatic polyether ketone resin (I) and the fluororesin (II) of 45:55 to 10:90,
wherein the aromatic polyether ketone resin (I) is a polyether ether ketone,
wherein the aromatic polyether ketone resin (I) has a melt viscosity of 0.10 to 1.50 kNsm −2 at 60 sec −1 and 390° C.,
wherein the fluororesin (II) comprises 90 to 99 mol % of tetrafluoroethylene and 1 to 10 mol % of the perfluoroethylenic unsaturated compound represented by formula (1),
