なされている。[Prior art] Polyetherketone resin has traditionally been used as an engineering plastic material with excellent heat resistance, flame retardance, and chemical resistance, especially in fields such as electrical and electronic equipment and vehicle equipment such as automobiles. I've been However, this resin does not have satisfactory non-adhesive properties, sliding properties, and high temperature rigidity, and cannot be applied in the field of office equipment such as copying machines, which require these properties. In addition, non-stick properties can be achieved by adding fluororesins such as polytetrafluoroethylene, polytetrafluoroethylene-hexafluoropropylene copolymer, and polytetrafluoroethylene-perfluoropropylene copolymer to polyetherketone resin. Attempts have also been made to improve the sliding properties.

れないという問題が新たに生ずる。In this case, in order to impart sufficient non-adhesion and sliding properties to the resin composition, it is necessary to add a considerable amount of the fluororesin described above, but if too much fluororesin is added, the resin composition Mechanical strength, especially high-temperature rigidity, which should be maintained cannot be maintained. In order to compensate for this drawback, it may be possible to use fibrous reinforcing nets such as glass fibers or carbon fibers, but in order to maintain the above-mentioned sufficient strength, it is necessary to add a considerable amount of these. In that case, new problems arise such that anisotropy and warpage occur due to the orientation of the fibrous reinforced side, and the mating material is easily damaged during sliding, making it impossible to obtain sufficient lubricity.

There is a problem that a resin composition has not been obtained, and it has been a challenge to solve these problems.

This method employs a method of adding 10 to 90 parts by weight to form a polyetherketone resin composition. The details will be described below.

and Arg are aromatic residues at least one of which has a diarylether bond forming part of the polymer main chain, and Ar+ and ^rt are covalently bonded to the carbonyl group via the aromatic carbon atom. ) The repeating unit represented by () alone, or this repeating unit and other repeating units represented by () may be used in an amount of 50 monomers (1%) to the extent that the original properties of the polyetherketone resin are not lost. The polymers coexisted in an amount of approximately . Suitable polyetherketone resins include those having repeating units such as,
These are commercially available, for example from ICI UK as VrCTREX-PEEK or VICTREX-PEK. Incidentally, a method for producing polyetherketone is disclosed in JP-A-54-90296 and the like.

A method for producing a copolymer with 1-difluoroethylene is disclosed in Japanese Patent Publication No. 49-32785, etc., by combining 3.3.3-trifluoro2-trifluoromethylpropene and 1.3-trifluoro2-trifluoromethylpropene. It is produced by copolymerizing difluoroethylene with ethylene in a predetermined solvent, in which case the molar ratio of both substances is in the range of 1:9 to 9:1, and about -15°
The copolymerization is carried out in a temperature range of about 80°C. An example of such a copolymer is CM-X manufactured by Aujimonoto, USA.
